Hayden Panettiere and ex- boyfriend Milo Ventimiglia will join other Heroes cast and crew in creating artwork for a silent auction to benefit Austism Speaks. The auction is scheduled to be held on April 19 at the Avalon Hollywood in Los Angeles. Hayden Panettiere has always been a big supporter for the cause of austism treatment and its awareness, having also helped raise money for charities working towards it.

The Office ‘s Rainn Wilson will host the event, which will also feature musical performances from Band From TV, a celebrity troupe that includes Heroes stars Greg Grunberg on drums and Adrian Pasdar on guitar. The one-night only, star-studded concert event will be held Sunday, April 19 at 5 p.m. at the Avalon Hollywood in Los Angeles.

Last year Hayden was involved in raising funds at a charity event for the cause of spreading awareness of autism and also to raise money for families that cannot afford autism treatment. Autism Speaks is USA’s largest autism science and advocacy organization.
