Monique Lhuillier Spring 2012Kristen Stewart was a guest on 'The Tonight Show with Jay Leno' in New York City.
The Twilight actress looks hot in her blue and black colorblock Monique Lhuillier sweetheart strapless dress.
I am delighted that she is finally letting her hair down.
She finished off her look with long locks and black peep-toe heels.
