Jennifer Lawrence looked like the girl on fire at the Christian Dior show during Paris Fashion Week Monday — but it wasn't because of her glowing tan!

The 23-year-old Oscar winner let her side boob do all the talking as she sat pretty in the front row.

Our gal J-Law looked effortlessly beautiful in a white frock from the fashion house's Resort 2015 collection — go figure. She completed the sexy look with killer black-and-white strappy pumps.

Like the blonde beauty, these stars are also notorious for letting flaunting their sideavage (side + cleavage) hang out. Take a look at who joins J-Law in the side boob game!
