A ton of celebrities attended the 4th annual Pink Party on Saturday night… Heidi & Spencer, Jennifer Garner, Vanessa Minnillo, Kate Beckinsale, and a ton of others.  Check out the photos!

Jennifer Garner is not the best dresser at these events.  It’s cool to be conservative, but that shirt does nothing for her… and everyone else seemed pretty dressed up and she went with jeans?  Well, except for Kelly Rutherford wearing what could almost be considered hammer pants!
