Less than four months after having a baby, Rachel Uchitel is already a hot, bikini babe mama!

Tiger Woods’ infamous mistress, who gave birth to her first child with husband Matt Hahn in May, stripped down and showed off her already slimmed-down bikini body over the weekend during a South of the Border getaway, and Breaking Celebrity News has the photos.

Uchitel and her hunky hubby enjoyed a romantic vacation at the Villa del Palmar Cancun, where they took long walks on the beach, spent afternoons at the pool, got massages at the resort’s Village Spa and also played a little volleyball and football.
