Jennifer Lawrence face palms Emma Watson at Christian Dior show in Paris

The actress offers up yet another one of her signature bouts of playfulness

Jennifer Lawrence exercised her seemingly innate ability to liven up every glamorous event yesterday with her weirdest incident to date – shoving her hand in Emma Watson’s face.

It was all very jovial and Watson seemed to take the face-palm with good humour, but still… Why? The two were posing for pictures at Christian Dior’s latest couture show in Paris, when Lawrence presumably got bored and gave photographers something much more entertaining to look at.

Watson, who is probably not used to having hands batted in her face, handled the situation deftly – and carried on having her picture taken like a good Hollywood starlet.

The two went onto sit alongside Dior CEO Sidney Toledano on the show front row, making for more conventional photo opportunities that the brand was possibly more satisfied with. Then Lawrence went backstage and was pictured laughing with the brand's sombre creative director, Raf Simons.

Other high-profile names to have attended the event in Paris included Marion Cotillard, Charlize Theron and boyfriend Sean Penn.

In March, someone with too much time on their hands merged the faces of Watson and Lawrence in Photoshop to create an 'internet goddess'.
