Rihanna who?

Chris Brown may have a new love interest.

Brown, who recently tested positive for marijuana during the probation hearing for his infamous 2009 assault on then-girlfriend Rihanna, was photographed cozying up to Pussycat Dolls lead singer Nicole Scherzinger at Hollywood hotspot Supperclub.

A witness told X17Online the two even locked lips.

“They were dancing close for a while and being all touchy-feely and finally Chris leaned into her,” a source inside the club told the Web site. “She put her head on his shoulder and they started kissing! I couldn’t believe Chris was being so obvious about it!”

Shortly after reports of their alleged make-out surfaced, Scherzinger’s rep insisted to TMZ that the pop star was simply talking (albeit very closely) to her friend.

“There is absolutely no truth to the ridiculous story … The photos that have surfaced are old friends who were trying to talk at a very loud club.”

The rep adds, “I guarantee there will be no photos of them kissing.”

Brown was romantically linked to Karrueche Tran but they reportedly split in July with Tran tweeting “the end” last week. Scherzinger allegedly called it quits with longtime love Formula One racer Lewis Hamilton but has been spotted with him multiple times since. The singer was linked to her “Dancing With The Stars” partner Derek Hough, as well as former “X Factor” host Steve Jones. And, it gets juicier—she’s reportedly hooked up with Brown’s arch enemy, Drake.
