Jansen Panettiere Supports Singing Hayden in Orange County

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!
