Kate Beckinsale stepped out to the Joel Silver Memorial Day party in Malibu yesterday and took husband Len Wiseman and her 10-year-old daughter Lily with her. Kate looked beautiful - obviously this wasn't a t-shirt and cutoffs kind of party. Bet they didn't have any cheap beer or bad coleslaw, either.
Here's another shot of the stunning family; looks like Len took a more casual approach. I'm guessing he was the only one in their crew to take part in the water balloon fight.
