Jennifer Lawrence 'slaps' Potter star Emma Watson

She's been busy filming the final two instalments of The Hunger Games, but it looks like Jennifer headed to hotter climes once the production wrapped.

The Oscar-winning actress looked very tanned as she arrived for Dior's Paris Fashion Week Haute Couture Fall/Winter 2014/2015 show.

But despite her chic demeanour, the playful side of Jennifer came out, when she palmed Emma Watson in the face as they were posing for pictures back stage.

Lawrence kept on innocently smiling while Emma seemed to laugh it off as just another prank made by The Hunger Games star.

The American actress is known for her red carpet photo bombs and comical capers during events, and even was pictured trying to steal Lupita Nyong'o's Best Supporting Actress Oscar after she lost out to the 12 Years A Slave star at this year's Academy Awards.

Jennifer was certainly looking a lot more tanned than Emma, as her bronzed skin was accentuated by the light colour of her dress which featured a grey top and a green and black ink stain pattern.

Her glowing skin was intensified by the use of black kohl and shimmering brown shadow around her eyes and a particularly nude lip colour.

A pair of light pink pearls could be seen shining in one of her ears while her tousled cropped hairdo covered the other.

The actress completed the look with matching accessories no doubt supplied by the design house she was in Paris to celebrate, having worn more than her fair share of Dior couture gowns.

Lawrence sat on the front row near Emma Watson, and joined a host of Hollywood stars - including Charlize Theron and Sean Penn, Marion Cotillard and Rosamund Pike - and former reality star Olivia Palermo to watch Dior's new season designs be walked down the catwalk.

After the show, Lawrence headed backstage to congratulate head designer Raf Simons on his latest sartorial offerings, and on the way she had put on a black leather jacket.

No doubt being in Europe, Jennifer will try and make some time to see her boyfriend Nicholas Hoult, the British actor she met while filming X-Men: First Class.

The couple have been separated lately because of her work commitments on Mockingjay parts one and two, which concluded in Berlin on June 20th.
