We are excited to welcome Audi and Best Buddies supporting guests, including California's Governor and First Lady Arnold Schwarzenegger and Maria Shriver, legendary actor and director Clint Eastwood, Lacey Chabert of Mean Girls and TV's Party of Five, The Bachelor's Andy Baldwin and Tessa Horst, celebrity trainer Kim Lyons, Gunter Schlierkamp from Beerfest and The Hulk, The Ex-Wives Clubs' Marla Maples, actor Greg German and Adrian Pasdar from TV's Heroes and many others to help us raise money to further Best Buddies' great work."
