Is 2010 the year of the thong?

It's been a while since the rise of the up-the-crack fabric strip, and although Carla Gugino in Sin City and Jaime Pressly in Poison Ivy 3 will always hold special spots in our hearts and parts with their spectacular thongs, it's time for some new meat. Seat meat, that is.

Now that Kristen Stewart's given us two different views of her butt-flossed booty beauty in Welcome to the Rileys, Natalie Portman has stepped up to the plate to lay some cheek action on us.

In our Top 10 Hottest Thong Shots list from a year ago, Natalie was firmly planted at #1 thanks to her skincredible G-string scenes in Closer.

Now, the skintrepid sex kitten is about to defend her title, thanks to a highly memorable scene from the red band trailer for her upcoming movie, Your Highness.

Have a look at the trailer here, and the isolated thong video/pics here. Thongs are back! Back up the crack, that is.

UPDATE: One of our computer skingineers noted that it appears Natalie is wearing a chastity thong--note the thickness and the fact that it appears to be made out of metal. Who's got the key?
