The birthday girl loves her bikinis!

LeAnn Rimes turned 29 on Sunday, and the singer-actress hit the beach in Malibu, Calif. the day before with hubby Eddie Cibrian and stepson, Mason. Wearing her typically tiny two-piece swimsuit, Rimes playfully posed for the camera as she showed off her toned physique.

But Rimes didn't just don one bikini Saturday. She showed off her taut figure in three different skimpy suits throughout the day!

So what did Rimes' hubby, 38, get the birthday girl? One of only 13 Celine bags, according to Rimes' Twiter. "OMG… Speechless!" she wrote. "My husband is amazing."
