Pregnant Uma Thurman on a yatch in St. Barts!

Pregnant actress Uma Thurman was photo'd on a yatch in St. Barts. She's there on a vacay with her kidlets, Maya, 13, and Levon, 10, and her mom Nena von Schlebrugge over the weekend.

Doesn't she look fabulous in that swimsuit — accentuating the belly with the stripes? And she's brave going strapless while preggers! I could never do it....

Speaking of stripes, I'm on an great, yummy diet, and Josh-O and I bought a stationary bike over the weekend. The pounds are starting to "fall" off, and I'll be wearing stripes like the celebs do in no time...!

Love!
