Reese Witherspoon, Drew Barrymore, Cameron Diaz’s Girls Vacation In Mexico [PHOTOS]

Nothing like a getaway with the girls to blow off some steam and forget about work, babies and other demands of the rough life of being a Hollywood star.

New moms Reese Witherspoon and Drew Barrymore flew to Mexico to show off their bikini bods in a relaxing beach escapade with single pal Cameron Diaz. The trio lounged in the sand of Tulum, in the southeast of the country, on Sunday and Monday.

They stayed in the exclusive eco-friendly Amansala Resort where they enlisted in Bikini Bootcamp -- the same place Demi Moore visited over the holidays. They got pampered by daily massages and treatments, and joined yoga, dance and cardio classes. They also took some time off to take a dip in the beautiful blue Caribbean, where Drew and Reese revealed healthy post-partum figures and Cameron showed off her impossibly perfect abs.

"It was a girls trip," an unnamed source told Radar Online. "No husbands nor babies. They looked like really good friends who were having a blast."

Reese gave birth to her third child, Tennessee James, with husband Jim Toth in September 2012, and Drew welcomed her first baby, little Olive, with Will Kopelman, in November 2012.
