LOS ANGELES, July 10 ― Jennifer Lawrence is just as famous for her hilarious antics during photo shoots as she is for her acting roles, but she seems to have recently outdone herself.

Attending Paris Fashion Week, Lawrence met “Perks Of Being A Wall Flower” star Emma Watson, and the two posed nicely all day together, resulting in hundreds of very similar photos.

Eventually, the monotony became too much for Jennifer, who out of nowhere slammed her palm into Watson's face, catching her by surprise and knocking her back. Meanwhile, the “Hunger Games” star kept the same sweet expression on her face, as if nothing has changed.

It looks like this is just typical Lawrence hi-jinx and all in good sport, and hopefully Emma saw the funny side of the prank.

Lawrence is definitely the one to watch at all red carpet events, having previously photo-bombed Taylor Swift and the Golden Globes, not to mention her “trips” to the Oscars. ― Cover Media
