Reports today are claiming that Twilight hottie Robert Pattinson and Harry Potter starlet Emma Watson are to get steamy in a lusty new art-house flick.

The pair are said to have signed on for the remake of Dark Arc, a dark comedy about love, lust, art and power. Casey Affleck is being considered to make up the film's 'love triangle' between an artist, a graphic designer and their inspiring muse.

Robert and Emma have previously starred together in Harry Potter and The Goblet Of Fire. Just last week, Emma made headlines for apparently slamming Twilight - of which Rob is the lead star - at a press conference, saying: "Harry Potter is not Twilight, we're not selling sex."
