Katy Perry wasn't the only Bachelorette celebrating with her hot friends this past weekend. While Katy was in Vegas with Rihanna, Nicole Richie was in Cabo San Lucas, Mexico with good pal Christina Aguilera.

Nicole was photographed hanging out with her girlfriends in a cute pink bikini, proving motherhood has done her body good. Just a few years ago she raised eyebrows with her super frail figure.

Lilo's ex Samantha Ronson also flew south to help Nicole celebrate. The ladies lounged poolside all day and hit the town later that evening for an intimate dinner.

Nicole was reportedly checking her BlackBerry like crazy, but isn't that what most moms do when they're away from their kids?

Nicole and Joel haven't announced when they're planning on tying the knot, but we're assuming its soon if the bachelorette party is already done with.
