Kristen Stewart Bares It All

Whoopsies, is that Kristen Stewart‘s thong?! 

Some die-hard Twilight fans have uncovered a slight mistake in the New Moon trailer. Or is it? Who knows!

Towards the end of the New Moon trailer, which debuted at the MTV Movie Awards, Jacob (Taylor Lautner) runs towards Bella to save her from the vicious fangs of Laurent (Edi Cathegi). 

At around 1:33, a flash of pink thong appears as Jacob transforms into a wolf. 

Ha! We wonder what Rob Pattinson thought about that one?
