It may feel like Chevy Chase hasn't been around for awhile, but this has been quite the week for him. He celebrated his 64th birthday on Monday, and on Tuesday he headed to the premiere of Cutlass, Kate Hudson's short film that he starred in. However, the biggest news of the week is that Chevy is going to join the cast of Brothers and Sisters. He'll be playing Sally Field's boyfriend from high school. Sounds juicy and we love that Chevy is back in action and looking so stylish as well. Welcome back CC!
