Kate Beckinsale celebrated her birthday, jumpsuit style, at the Thompson Hotel in LA on Friday night. She was escorted by hot hubby Len and joined by BFF couples, the Beckhams and the Parkers. Victoria showed off her stems in her favorite pink heels while Eva lightened things up in yellow. But she might have wanted to loosen up that top (damn those poor boobs look like they're in pain). Even Dustin Hoffman and his wife made an appearance. It's always fun to see these gorgeous celebrity couples partying together, and we wish a happy birthday to Kate who turned 35 on Saturday!
