0 Oh look Keira Knightley is kissing a man whos not her fianc *gasp *

She only got engaged a month or so ago but it looks like already Keira Knightley has got bored off James Righton.

Not really… it was just for a film. Keira is currently filming Can A Song Save Your Life? in New York.

And she’s snogging Mark Ruffalo, her co-star.  To be fair it doesn’t look like she’s that into it because she’s seen pushing him away after their passionate embrace.

In the film Keira plays a dumped lover who embarks on a new romance. Maroon 5’s Adam Levine also stars in a film and plays her first love.

Their characters arrive in New York with the aim of pursing a musical career together.

Adam’s character then dumps her because he thinks he’ll have a more successful career without her.

Of course, as you can imagine, Keira is the one who goes on to be successful after she is discovered by a pro ducer(Ruffalo).  Sounds great.
