Reese, Cameron, and Drew Hit the Beach in Bikinis!

Reese Witherspoon sported a striped swimsuit while logging beach time in Tulum, Mexico, this week. She joined Drew Barrymore and Cameron Diaz on the girls' getaway, which reportedly included a bikini bootcamp program. While Cameron flaunted her figure in a colorful bikini and straw hat, Drew showed off her postbaby body in a retro polka-dot two-piece.

The tropical trip comes just a few weeks after Drew's 38th birthday. Drew, of course, has plenty to celebrate since she gave birth to her daughter, Olive Kopelman, late last year. Reese also welcomed a baby in late 2012 — her son Tennessee Toth entered the world last September. This isn't the first time we've seen Reese on the sand postbaby, as she wore a blue swimsuit during a family trip to Hawaii earlier this year.
