Back filming her NBC series, Heroes star Hayden Panettiere takes a telephone break and trades in her customary cheerleader uniform for a bikini on the Malibu, Calif., set of the hit show Monday…

Does this mean there will be Hayden Panettiere bikini scenes on the show this fall? A bunch of Heroes fans are probably hoping so!

Wow! Who’s that girl walkin’ by?

Oh, who are we kidding. We know exactly who it is. But Hayden Panettiere just looks so great sometimes, we can’t help but marvel at it. Seriously, she’s got the whole package - the personality, the array of talent, and magazine-cover good looks to boot.

When we see certain Hayden Panettiere pictures, we just have to pay tribute to our favorite actress (and singer). Go Hayden!

We wouldn’t object if Hayden Panettiere defied that “no parking” sign above her head in this photo and parked it right here in our office for us to bask in her awesomeness and talk to her all day. Alas, we’ll just have to watch Heroes.

She supports the troops - and who can blame her?

Hayden Panettiere paid a visit to the Walter Reed Army Medical Center while she was in Washington, D.C. on July 4. She brightened up the place - as she does just about every place she goes - and paid tribute to the men and women of the Armed Forces who make the ultimate sacrifice for their country.

A couple of pictures of Hayden Panettiere at Walter Reed …

The Heroes cutie had the privilege of meeting with the brave men and women who have been injured while fighting overseas at Walter Reed, which serves more than 150,000 active and retired personnel from all branches of the U.S. military.

As usual, Hayden Panettiere shows what a grounded, sweet girl she is, paying a visit such like this. Her heart is in the right place!

This came during the same trip in which Hayden sang at the Capitol Fourth concert in front of more than 500,000 fans in Washington.

Maybe you’ve noticed that despite her very young age (17 for another three weeks), Hayden Panettiere has become a major sex symbol.

This trend has reached new heights with the newest edition of FHM in the UK, which features our girl in a seductive pose. Gulp. Not that we’re complaining, as Hayden looks great in anything and anywhere.

Anyway, here’s the Hayden Panettiere shot from the UK FHM …

Is it hot in here? Or is it just Hayden Panettiere?

Probably a little of both. It is July 30, after all. It’s a tad humid outside. Needless to say, we’re psyched for Heroes to return, as it gives us a chance to see our girl once a week for a full hour. But until September, magazine features and photos like this are certainly appreciated!

The awesome cheerleader Claire Bennet (Hayden Panettiere) is indestructible on Heroes. And hopefully in real life. We’d hate to see anything happen to her!

Seen here with co-star Milo Ventimiglia, our girl is shown behind the scenes of the NBC hit series in photos made available by the network.

Here are a few photos of Hayden Panettiere from the set:

It would be wrong - on many levels - to go on about how good 17-year-old Heroes star Hayden Panettiere looked yesterday on the set of her hit show.

Either way, she didn’t play on her looks the way so many lovely young stars do, batting eyelashes and making sure you get a good look at the assets.

She seemed more like a perfect-attendance, student council president type … who just happens to be magazine-cover gorgeous.

Hayden Panettiere did, however, provide one of the more, troubling moments of the morning, and this one was straight out of a Buffy the Vampire Slayer rerun.

As a TV with Meevee correspondent toured the set, Hayden Panettiere made very clear that we won’t be seeing her in any Lindsay Lohan-style misadventures.

“I have an allowance that I get, the money was never made apparent to me, it was just, ‘This is what you love to do.’ I was raised completely as a normal kid,” she said.

“I take out the trash, I walk the dogs, I make the bed, I vacuum… I’m not allowed to leave the house unless I make the bed and make sure that everything in my room is put away.”

Hayden has a generous 1 a.m. curfew, however.

Besides the fans yelling “The cheerleader!” and pointing at her, there are some tough angles to being a pretty young star. Like the paparazzi waiting outside her house for her to leave.

“You usually have cameras following you, which makes it more of a scene,” she said. “I went to Venice Beach the other day, you can sort of blend in with people, which is kind of nice. But then they see 10 cameras, and they’re like, ‘Who are they looking at? Who are they looking at?’”

She sighed and shook her head, and someone asked if she could understand what has happened to Lindsay Lohan and to other young starlets, and if it could happen to her. The answer to the latter was an emphatic no.

“I’m not surrounded by those kinds of people they’re surrounded by. You understand how it happens, you understand what they did wrong,” said the older sister of Jansen Panettiere.

“But it’s so, like, controllable. When you’re putting nasty white powder up your nose, that’s you putting it up there, no one else is putting it up there.”

On Heroes, Hayden Panettiere, as you surely know, plays the cheerleader, Claire Bennet, whose super power is healing. Halfway through the tour, the prosthetics guys had a selection of fake body parts laid out on a long table.

Hayden Panettiere and her little brother, Jansen Panettiere, 13, attended the Orange County Flyers game at Cal-State Fullerton Saturday in Fullerton, Calif.

The Heroes cheerleader sang with co-star Greg Grunberg’s all-star Band From TV. Backed by the band, Hayden performed Meredith Brooks’ “B!tch” and Alanis Morrisette’s “Ironic.”

Hayden’s boyfriend, Stephen Colletti, was also there to cheer her on.

Panettiere joined Grunberg on drums, along with Desperate Housewives‘ James Denton on guitar, House’s Hugh Laurie on piano and Bachelor star Bob Guiney and Kitchen Confidential actress Bonnie Somerville on lead and backing vocals.

Hayden Panettiere, 17, was also seen out and about Saturday on the streets of Los Feliz, Calif. Her debut album comes out later this year!

It’s the ultimate high-school girl’s fantasy.

You’re on a sound stage, surrounded by a hairdresser, makeup artists and racks of beautiful clothes. A camera crew follows you as you shoot a TV commercial for which you’re getting paid big bucks.

Welcome to the world of Hayden Panettiere.

She’s been in front of the cameras since her audition for a commercial at eight months old, “before she could even sit up straight,” says her mom, Lesley. Panettiere, who turns 18 August 21, stars on Heroes as Claire Bennet, who inspired the show’s catchphrase “Save the cheerleader, save the world.”

At this Sunday shoot, Hayden Panettiere is joined by her 12-year-old brother, Jansen Panettiere, who’s followed his big sis into show business.

In the Nickelodeon movie The Last Day of Summer (premiering Friday at 8 pm/ET) he plays a boy who dreads going to school and wishes Labor Day would last forever.

Don’t we all…

As they sit down to talk with TV Guide, Hayden Panettiere — at her mother’s prompting — starts to interview her brother.

Hayden Panettiere: Why are you so handsome?

Jansen Panettiere: ‘Cause I got good genes from my mom.

Hayden: You are hurting Dad’s feelings.

Jansen: [To his father, Skip, who is also at the shoot] Dad, you gave me a very balanced body. [To Hayden Panettiere] Now, why are you so gorgeous?

Hayden: Because I am related to you. Why did you get the dark skin and the dark eyes?

Jansen: It is a lot harder for me because [Hollywood] likes blond, blue-eyed kids.

Hayden: No one wants him to play white. He is doing a feature film, The Perfect Game….

Jansen: I play a Hispanic baseball player from the 1950s.

Hayden: What’s your character like in The Last Day of Summer?

Jansen: I don’t think he is extremely… energized? How do you say it?

Hayden: Energetic. You, by the way, are very energetic.

Jansen: Thank you for noticing. My character does not have the electricity that I have. During the film his confidence gets a total boot.

Hayden: Boot! You mean boost.

Jansen: Oh my god. I can’t work with her. [To his mother] Mom, Hayden is picking on me.

Dressed in a cute yellow sun dress, Hayden Panettiere and a female friend head to the movies in Los Angeles. See below…

As usual, Hayden Panettiere is looking stellar… albeit a little annoyed, perhaps, in the second photo. Oh well. Maybe she’s wishing it were Stephen Colletti attending the matinee with her. Hope she had fun in any case!

Heroes cheerleader Hayden Panettiere, who is also a budding singer, will make a guest appearance with fellow cast member Greg Grunberg’s all-star Band From TV this weekend, People reports.

“I sang with them at the wrap party for our show,” Panettiere, 17, said Tuesday at a party in L.A. celebrating Heroes and the rest of NBC’s fall season.

“I saw them and said, ‘Anytime you guys want me to perform with you, I’m totally up for it.’ ”

Panettiere, who has a debut album on the way and recently made headlines with her performance at the July 4 concert in Washington, D.C., will take the stage with Grunberg and his fellow actor-musicians on Saturday in Orange County, Calif. at California State-Fullerton.

This special Hayden Panettiere performance will follow the Orange County Flyers’ minor league baseball game.

The Band From TV is a rock cover band featuring the aforementioned Grunberg on drums, Desperate Housewives‘ James Denton on guitar, House’s Hugh Laurie on piano and both The Bachelor star Bob Guiney and Kitchen Confidential actress Bonnie Somerville on vocals.

All the proceeds from the Band From TV’s concerts and upcoming CD and DVD projects go directly to charity.

For her part, she may be an actress by trade, but Hayden Panettiere will jump at any chance to practice singing onstage.

“I have terrible stage fright and [with an album coming out] I’ll need to go on tour at some point, so I need to practice,” she said.

How serious is Hayden Panettiere’s stage fright?

“The Fourth of July performance in Washington, D.C., was so nerve-wracking that I’m surprised I even made it on stage,” she admits.

But Greg Grunberg laughed off Panettiere’s claims.

“Give me a break,” he said. “She just played in front of like 500,000 people!”

This weekend’s audience is expected to be closer to 5,000.

“That’s like the biggest audience we’ve played. It’s really exciting,” he says. “We’re going to do a whole set, then [Hayden Panettiere] is going to do two amazing songs.”

Tickets are $20 and still available at orangecountyflyers.com. Wondering what, exactly, will Hayden Panettiere sing?

“I’m singing Meredith Brooks’ ‘Bitch,’ and then I’m singing Alanis Morissette’s ‘Ironic,’” she says. “It’ll be fun!”
