Just a few hours after stopping us in our tracks with her stunning appearance [1] at the X-Men: Apocalypse premiere in London on Monday, Jennifer Lawrence [2] caught our attention again [3] when she hit the town with a few friends. Not only did the actress show off her killer figure in a sexy bustier dress, but her frosty blond hair [4] gave us major Emma Frost vibes. The big night out comes on the heels of her costar Sophie Turner revealing a hilarious story about Jen that involves her punching Sophie "in the vagina [5]." See more pictures from her latest appearance ahead, and then check out her best bikini moments [6].
