R-Pattz and Kristen Stewart caught kissing at Cannes

London, May 25 (ANI): Robert Pattinson and Kristen Stewart were spotted having a long coupley kiss at a nightclub in Cannes, finally putting speculations of their off-screen relationship to rest.

The couple were at Les Marches nightclub, after Pattinson turned up to support his girlfriend at the premiere of her new film, 'On The Road', at Cannes.

They hung out on the balcony while Pattinson, 26, drank a beer and still wearing his suit from the red carpet and Stewart, 22, in a leather jacket, the Mirror reported.

They've been dating since the first 'Twilight' film in 2008, and have been spotted in bars, on holiday, at his parent's house - and she even referred to him as "my boyfriend" in a recent interview.

The couple will be in Cannes for a few more days, as Pattinson's new film 'Cosmopolis' also premieres at the film festival. (ANI)
