She’s is normally pretty reserved when it comes to dressing up for red carpet events.

But it’s seem Jennifer Lawrence was in the mood for something a little racier when she attended  Dior’s Paris Fashion Week Haute Couture Fall/Winter 2014/2015 show on Monday.

The Hunger Games star flashed some serious sideboob beneath her white dress before revealing her playful side as she palmed Emma Watson in the face as they were posing for pictures back stage.

Fake tan, sun bed or holiday? Jennifer Lawrence looks remarkably bronzed as she arrives for the Dior Paris Fashion Week Haute Couture Fall/Winter 2014-2015 show

Daring: Jennifer revealed some sideboob beneath her elegant gown

Faceplant: Jennifer messed around with Emma Watson putting her hand in her face

Hilarious: Emma took Jennifer’s joke very well as they hung out after the show

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.

Tanned: Looks like Jennifer Lawrence has been on holiday or hitting the fake tan judging by her bronzed skin.

That’s better: Jennifer stops playing games to take a normal picture with Emma – who looks slightly worried

Congratulations: Jennifer praises Raf Simons, Dior head designer, after the show

Hugs all round: Jennifer has worn more than her fair share of Dior dresses, having worn two couture numbers to the last two Oscars

Cover up: Jennifer tried to protect her modesty as she made her way to her seat at the show

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.

Radioactive: The nude lip and shimmering eyeshadow enhanced Jennifer’s tan
