Jessica Alba took a dip in the pool during her Cabo vacation this week. Jessica wore a bikini, showing off her fit postbaby body, for the swim and shaded her face with a hat. She had daughters Honor and Haven as well as husband Cash Warren by her side for the sunny afternoon of fun, which continued yesterday. Jessica covered up in a maxi dress and hung out under an umbrella with her youngest child. The whole Alba-Warren foursome made the trip to Mexico on Tuesday after celebrating Christmas at home with family and friends. They're just one of many famous faces spending the extended holiday south of the border, including George Clooney and his girlfriend, Stacy Keibler, and Cindy Crawford and Rande Gerber.
