LeAnn Rimes slipped into a sexy bikini while vacationing with her shirtless husband Eddie Cibrian in Cabo San Lucas on Friday. The couple was joined by a group of pals as they relaxed by the pool at their villa. Eddie and LeAnn are no strangers to a Mexican getaway, and they headed to Cabo earlier this week to celebrate the 40th birthday of a friend. LeAnn took to Twitter to announce her vacation plans and has been busy sharing photos and videos of the fun. She also tweeted a message this morning, saying, "Happy Saturday! On the agenda....friends, sun, ocean & tequila!"
