Uma Thurman hit the high seas over the weekend, showing off her baby bump for the first time!
The 41-year-old, who announced last month that she is expecting her first child with businessman boyfriend Arpad Busson, was spotted frolicking on a yacht in St. Barts over the weekend.
The actress sported a black-and-white striped one-piece swimsuit for her dip in the ocean, and donned various cover-ups while on board the boat.
Baby will make five for the couple. Uma has two children -- 13-year-old daughter, Maya and 10-year-old son, Levon -- with ex-husband Ethan Hawke, while Arpad has two sons -- Arpad Jr., 14 and Aurelius, 9 -- with ex Elle Macpherson.
