She once starred in a film called Prime, and it's not hard to see why.
Uma Thurman, who turned 40 in April this year, showed off her incredible bikini body while on holiday with boyfriend Arpad Busson in the Aeolian Island of Filicudi.
Wearing a taupe two-piece, Uma looked toned and tanned as she made the most of the sunshine and played in the water.
The actress enjoyed a meal with on-off boyfriend Busson at romantic restaurant The Little Mermaid, before heading back to the yacht where she displayed her impressive diving skills.
Mother-of-two Uma looked amazing in the bikini, but recently admitted she has sometimes struggled with her looks.
She said: 'My mother always made it very clear to me that, whatever you look like now, you're going to look worse later. Don't get too attached to your beauty because it's not yours to keep.
'Don't go around thinking that it's some big bonus and that you can count on it. And I was not classically attractive. I've always been sort of an acquired taste.'
