Kate Beckinsale shows off her smoking hot bikini body while vacationing in Mexico with husband Len Wiseman, and Breaking Celebrity News has all the best pictures.

The 37-year-old actress caught some sun sporting a bright blue ruffled bikini, sun hat and black spectator shades.

She and Wiseman, a director -- they met on a set, of course -- put their feet up as they relaxed poolside while enjoying a light afternoon lunch.
