She tried to avoid too much sauciness in her role as the latest Cadbury's Flake girl.

But judging by this racy picture of her sharing a steamy kiss with a co-star, Joss Stone has taken no such measures in her latest project.

The singer promised her first ever film role would see her share a passionate smooch with a female actress and romantic comedy Snappers does not disappoint.

Ironically, given Stone's own clashes with the press, the British film is about an actress who is trying to escape the paparazzi.

She ends up at a local caravan park, where Stone's character - a lesbian bingo-caller - works as a red-coat style entertainer.

There are also some intriguing scenes with an Elton John lookalike which have yet to be explained.

Speaking previously about the role, she said: "I just wanted to challenge myself. There are things in the film that are going to really push the boundaries, and that excites me.

"I can also confirm there will be a long lingering French kiss, but it won't be with a male."

Filming has been taking place in and around Torquay and Paignton this month.

The 20-year-old singer, from Devon, is also producing the soundtrack for the film.

She said: "I am bringing my guys over from America for three months to work with me on the soundtrack and original score.

"I have already started writing songs for Snappers, I have been sleeping with a pad and pen in bed with me for the last three days and I keep jumping out of bed in the middle of the night to jot lyrics down."

The film, which will premiere in September, also stars Caroline Quentin.
