It's a monu-mam-tal day for fans of pixie-blond Kirsten Dunst, since her new(d) movie All Good Things opens today, featuring the first real, clear nude scene from the Crazy/Beautiful babe.

Or IS it her first nude scene?

In a new interview with Vanity Fair, Kiki admits that the butt we saw in Marie Antoinette isn't, as previously thought, a body double!

"I was naked in Marie Antoinette, but that was just from behind," she says.

Furthermore, Dunst and her cute bunst says that All Good Things is just the beginning for All Nude Things, and she'll grin and bare it once again in her next film, which is directed by noted skin-meister Lars von Trier (Antichrist, Manderlay, Breaking the Waves).

"After this, I also have a nude scene in Melancholia. So they’ll get used to seeing me naked. Trust me, they’ll be over it by the next film."

Trust Mr. Skin, Kristen: we'll never be over it.
