Robert Pattinson is NOT dating Uma Thurman — despite recent reports to the contrary!

The romance rumor mill went into overdrive when it was announced that Thurman — Pattinson’s costar in the upcoming movie Bel Ami — had split from her fiance, Arpad Busson.

It was even claimed Uma’s romance with the hunky Brit was why she split from the wealthy Swiss financier.

But a rep for the Kill Bill star has spoken out to debunk the claims.

“That is actually funny,” the spokesperson told GossipCop. “Uma hasn’t even been in the same room as Pattinson.”

Thurman will play a wealthy woman who is seduced by Pattinson’s younger character in the movie, an adaptation of Guy de Maupassant’s 1885 novel.

Meanwhile, it has been claimed that Pattinson and his girlfriend, Kristen Stewart, have been drifting apart.

“Rob doesn’t want anything heavy right now, so he really has had enough of the whole thing and is spending a lot more time with Stephanie,” a source recently told Britain’s Now magazine.

“He just wants to hang out with lesser-known friends and take time out from all the craziness in his life, as it’s all got a bit too much.

“Even for Rob, the attention has been overwhelming and sometimes he just wishes it could all go away.

“He’s become a lot more reclusive and there’s a growing distance between him and Kristen.”
