Kate Beckinsale: Ruffled Bikini In Mexico

Kate Beckinsale shows off her amazing body while vacationing in Mexico with husband Len Wiseman in Mexico on Saturday (January 15).

The 37-year-old actress wore a Juicy Couture bikini and also sported her new blonde look while enjoying the sun poolside.

In March, Kate will probably switch back to darker hair as she prepares to film Underworld 4: New Dawn. She returns after skipping out on the third installment of the action vampire series.
