LeAnn Rimes rang in her 29th birthday with a smile – and a tan!
Accompanied by hubby Eddie Cibrian and his son Mason, the singer celebrated on Saturday by frolicking on the beach in Malibu, Calif., where she tied the knot in May.
Rimes donned three different teeny-weeny, cleavage-baring bikinis and was brought a cake with candles.
But enjoying some family fun in the sun wasn’t the only thing that brought Rimes joy on her big day.
