She was last seen letting her hair down on US talk show host Jimmy Fallon’s popular show, but it was back to business on Saturday as Jennifer Lawrence made promotional appearance at Cannes.

The 23-year-old actress was attending a photo-call for new film The Hunger Games: Mockingjay – Part 1, and she caught the eye in a smart white two-piece ensemble.

Jennifer’s outfit was all the more distinctive by virtue of its striking chest panel, fashioned to resemble a window through which a picturesque dreamscape had been created.

The image of a stone staircase set high above a desolate beach stood out as she posed for photos with co-stars Liam Hemsworth and Sam Claflin.

Jennifer matched her cropped, sleeveless outfit with a pair of snappy silver stilettos, and she was in high spirits as she laughed and joked with her hunky cast-mates throughout the promotional appearance.

The actress had previously turned heads as she left the Majestic Hotel shortly after jetting into the French Riviera on day four of the 67th annual Cannes Film Festival.

'When we’re busy, we agree to mutually ignore each other,' she said, explaining the pair's decision to do their own thing rather than have regular Skype calls.

'Not completely, but neither of us gets mad when the other doesn't text back or call.

'At least this way he's in the same boat as I am: We can go out and have our own lives and know that we have each other.'

The two actors met and fell in love on set of X-Men: First Class, and after breaking up for a spell rekindled their romance while working on the upcoming sequel, Days Of Future Past.
