Uma Thurman Pregnant Bikini Candids in Italy

Uma Thurman, who was wearing a revealing bikini while vacationing with boyfriend Arpad Busson in Italy, looks as if she may be pregnant with her third child.

The actress, who has two children from her previous marriage to Ethan Hawke, previously broke off her engagement to the billionaire Busson last year, but they reconciled soon after.

And how! The 40-year-old Thurman has never looked happier and healthier -- but is that a pregnancy glow she's sporting or just the look of love? (We've e-mailed her rep for confirmation, but as Thurman's on vacay in Italy, she couldn't be immediately reached for comment.) 12 more images after the jump.
