Kate Beckinsale adjusted her bikini bottoms on vacation in Mexico with husband Len Wiseman yesterday. Kate and Len spent their Summer and early Fall together in Toronto working on the remake of Total Recall, which she is starring in and he's directing. Now that they've finished up work on that highly anticipated project, it may be time to shift focus to one of their favorite holidays. Kate, Len, and her daughter, Lily Sheen, go all out for Halloween, and some of their couple and family costumes have included Frankenstein and his bride, Superman and Wonder Woman, and a devilish trio. We're excited to find out what they pick out this year, and, in 2012, we'll be seeing Kate in a number of sexy getups. She'll be back in her skin-tight Selene outfit for Underworld Awakening and kicking ass in Total Recall, and we'll see a slightly different side to her when she joins up with Mark Wahlberg in Contraband.
