Nothing to hide! Pregnant Ashlee Simpson and her hubby Evan Ross had no worries on Saturday, March 28, as they laid out by the pool in Los Cabos, Mexico. 

Simpson, 30, whom Us Weekly confirmed was pregnant in December, sunned her growing baby bump in a Merlot-colored bikini. The musician, who is already mom to son Bronx, 6, also wore a sheer, printed cover-up, while sitting by the pool with friends. See more pics of Ashlee's bump.
