Pictures: LeAnn Rimes Celebrates Her Birthday in Bikinis

Country singer LeAnn Rimes celebrated her 29th birthday by slipping into three skimpy bikinis as she frolicked on the beach in Malibu with her husband of four months Eddie Cibiran, who showed off his washboard abs in swimming trunks and a white baseball cap worn backwards.

During the day, the Rimes played on the beach with Eddie's young son Mason (someone please cover the kid's eyes?), whom he shares custody with 'Real Housewives of Beverly Hills' star, Brandi Glandville.

The young boy chased his stepmother, who continued to show off her ripped body in a mismatched bikini consisting of a peach-colored top and floral bottoms with ties at the side.

As the day wore on, Rimes slipped into her third and most daring bikini of the day, a tiny red crochet, which left little to the imagination. Even her discreet tattoo, which says 'Love,' was visible above her extremely brief briefs at the bottom of her back.

Cibiran could barely keep his hands off his super slim wife, as she leaned against him while they chatted with friends. At one point, Rimes treated herself to what appeared to be margaritas with salted rim.

The country star's beach celebration comes after she stepped out for a Mexican meal last night at the Mexican restaurant Red O in West Hollywood to celebrate her 29th birthday.

The singer flew in to Los Angeles on Friday morning so that she could enjoy the occasion surrounded by family and friends.
