Jennifer Garner Scarf Key Club skirt valet Hollywood

A dressed up Jennifer Garner was spotted at the Key Club on Sunset Blvd in West Hollywood the other night, and the mother of two rarely goes out after dark, so what was she up to?

Turns out the actress (along with several other famous faces, including Debbie Gibson) was at the live music venue for a fundraiser benefitting West Hollywood Elementary School's struggling art program. Ben wasn't anywhere in sight, but Jen didn't seem to mind his absence ... or the chilly weather!
