Celebrities gathered at the 4th Annual Pink Party cancer benefit in Los Angeles last weekend and whether the stars were dressed to the nines or opted for a more casual look, they all looked wonderful!

More photos after the jump!

Some the Hollywood stars who attended were:  Jennifer Garner, Kate Beckinsale, Brooke Burke (with husband David Charvet), Julia Louis-Dreyfus, Lori Loughlin and Marcia Cross.

It's nice when celebs lend their support to help important causes.
