Natalie PortmanNatalie PortmanShe crossed her heart that it would never happen.

But Natalie Portman has now taken the plunge...

And got her kit off in front of the camera.

She is normally such a shy lass.

But the hot scenes in her new film beg to differ.

And we're guessing there's many a man folk rejoicing.

Nat bares boobs and bot for the sake of her art form in her short movie, Hotel Chevalier.

But with a bod like hers it's almost a shame to keep it under wraps.
