From the Frontline of Fashion: Emma Gets Jennifer's Hand in Her Face

Let this be a lesson to celebs everywhere - if you find yourself near Jennifer Lawrence on the red carpet, be prepared. Emma Watson wasn't and get a faceful of JLaw's palm. The actresses were at the Dior show at Paris Fashion Week on July 7.

Jennifer is a regular menace on red carpets. When she's not tripping over herself, she's photobombing someone else. The last celeb to be JenLawrenced was singer Taylor Swift. So Emma really should have known better.

As it turns out, the Harry Potter star - lovely in asymmetrical monochrome and red lip - saw the funny side. No Expelliarmus charm needed.

Jennifer, who plays Katniss Everdeen in The Hunger Games films, wore a Dior ensemble in white.

Yes, Emma - you can smile now. It will be someone else turn to be JenLawrenced next.

Coming Up: Jennifer Lawrence Wears 5 of the Ugliest Dresses We've Ever Seen

Oscar-winner Jennifer Lawrence seems to have lost her fashion mojo. The Dior darling proved this by wearing a series of frankly ugly dresses at the premieres of her new film The Hunger Games: Catching Fire.

This sheer grey Dior dress with a bodysuit she wore to the Los Angeles premiere was a spectacular fashion fail, especially when compared to the pale Dior gown she wore to the Oscars earlier this year.

Equally unflattering was this Dior jacket and skirt over a crop top Jennifer wore to the New York screening.

Jennifer heaped ugly upon ugly in this Goth horror – by Dior of course - at the Paris premiere.

Jennifer fared little better with a black and orange Proenza Schouler knee length dress during the Rome photo call of the film. It's black but not beautiful. Sadly, the look left us cold.

Back to Dior, Hunger Games' Katniss tried sheer again at the Madrid premiere of the film but though her long legs were on display, it seemed like the actress forgot the bottom of her dress.
