LeAnn Rimes is living la vida loca on her honeymoon in Cabo San Lucas, Mexico -- or at least her teeny bikini looks like it's ready to party. Rimes and her new hubby, Eddie Cibrian, have been catching some rays south of the border during their romantic post-wedding getaway. The pair tied the knot in an intimate ceremony last month.

Rimes showed off her toned bod in a rhinestone studded, champagne colored bikini.

"They were very affectionate, always kissing, hugging, holding hands and laughing throughout the day," a source told Us Magazine.

Although Rimes took a lot of heat pre-wedding for her dramatic weight loss, the country crooner looks happy and healthy.
