Now that's one hot mama.

Uma Thurman wowed in a bikini while vacationing in Saint Tropez, France over the weekend. The 43-year-old mother-of-three showed off her post-baby body in a striped two-piece as she relaxed on a boat with boyfriend Arpad Busson and her children on July 6.

Thurman, who welcomed daughter Luna (full name: Rosalind Arusha Arkadina Altalune Florence Thurman-Busson) with Busson in July of last year, has two children with ex-husband Ethan Hawke -- daughter Maya, 14, and son Levon, 11.
