Eminem doesn't have a new girlfriend ... but his movie does have a title.

The Detroit-born rapper's semi-autobiographical film has, to this point, only been referred to as "The Untitled Detroit Project." But TV Guide reports the movie is now known as "8 Mile."

The title refers to Detroit's 8 Mile Road, which is considered the dividing line between the black and white communities in the city, the report said.

But the film's producer Brian Grazer tells TV Guide that reports of a relationship between Slim Shady and his co-star Kim Basinger -- who plays his mother -- are untrue.

"They're not having an affair. They're so not, actually," said Grazer.

Grazer speculated that rumours of the affair were sparked when Basinger and the rapper were seen leaving a restaurant together in Motown.

"If they were (having an affair), I would go, 'I don't know'," Grazer said. "But they're actually not".
