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.'

Uma is clearly making the most of her time off before she has to start promoting new movie Bel Ami, in which she stars alongside Robert Pattinson and Reese Witherspoon.
She will also soon start shooting the third installment of Quentin Tarantino's Kill Bill franchise, in which she will reprise her role as The Bride, but said previously the part takes an enormous amout of physical endurance.
She explained: 'It was demanding to take on such an incredible physical challenge and play a character who for so long is almost in a silent movie and then to wait until volume two, which is the more character-driven film.
'I had never read anything like this. You had to wonder where to begin to prepare for this part.
''This was the most physically extreme movie I have ever done.'
Uma will also be using her fame to protest against the use of children in armed conflict, when she stars as Sister Caroline in upcoming movie Girl Soldier.
Speaking about the role, Uma explained: 'This is a film that had to get made. It's beyond me that in this day and age the exploitation of child soldiers goes virtually unnoticed and unchecked by Western media.'
