Those chaps over at US GQ need to get themselves a calendar - stat. Only 13 years into the new millennium and they've already put together a list of the sexiest women that the years 2000-3000 have to offer. While we can't help thinking this might be a little premature, we've got to say we wholeheartedly agree with some of their choices. Beyonce as Woman of the Millennium? Yes please.

Meanwhile, Katie Holmes was voted the third Sexiest Woman of the Century (beating J-Lo, Britney Spears, Eva Mendes and Halle Berry) thanks to a rather naughty (and nudey) scene in The Gift, a film no-one seems to have watched. Katie is undeniably gorgeous but she wouldn't be our third choice for sexiest woman, but then we realised: this was the moment the cutsey actress shed the wholesome Joey Potter butter-wouldn't-melt-in-her-mouth Dawson's Creek image and became a bonafide babe in the eyes of mankind. So we've put together six more film moments that took some of our favourite actresses from clean-cut to femme fatale.

6. Sienna Miller in Alfie

A pair of Ugg boots, red pants and not much else in the remake of Alfie meant that all of a sudden, nobody was looking at Jude Law anymore.

5. Denise Richards - Wild Things

After playing an eager-beaver space-school graduate in Starship Troopers, Denise's next film was a little bit different. Wild Things, featuring a very naughty menage-a-trois with Neve Campbell and Matt Dillon, put Denise firmly into the Women We Lust After category.

4. Megan Fox - Transformers

Almost unrecognisable as Sydney Shankowski from short-lived sitcom Hope And Faith, it was Transformers that turned Megan Fox into pin-up extraordinaire.

3. Mila Kunis - Black Swan

Fresh-faced and cute as a button on That '70's Show, Mila did a serious 180 in Black Swan thanks to that scene.

2. Sarah Michelle Gellar - Cruel Intentions

From virtuous Buffy to evil stepsister, Cruel Intentions showed us a whole new side to SMG.

1. Scarlett Johansson - Match Point

That platonic (or was it?) friendship between Scar-Jo and Bill Murray in Lost In Translation seemed a million miles away when we saw the heated affair she had with Jonathan Rhys-Meyer in Woody Allen's Match Point.
