Chris Brown shocked clubgoers at a nightclub in Los Angeles on Tuesday, Sept. 25.

Brown was spotted kissing singer and TV judge Nicole Scherzinger at the Black Pyramid Party at Supperclub.

An eyewitness at the club told X17 that the two singers were "dancing close for awhile."

"(Brown and Scherzinger were) being all touchy-feely and finally Chris leaned into her. She put her head on his shoulder and they started kissing! I couldn't believe Chris was being so obvious about it!" said the source.

Since the photos surfaced in several reports, Scherzinger's publicist came forward and defended the images through a statement.

"There is absolutely no truth to the ridiculous story," Scherzinger's rep told TMZ. "The photos that have surfaced are old friends who were trying to talk at a very loud club. I guarantee there will be no photos of them kissing."

Brown's public display of affection came as a shock to the party's attendees. Earlier this month, the "Transform Ya" singer hugged and kissed his ex-girlfriend Rihanna live on television during the 2012 MTV Video Music Video Awards on Sept. 6.

Brown has been dating model Karrueche Tran since late 2011 despite the obvious tete a tete with Rihanna. Last week, Tran tweeted "the end," which sparked rumors the pair may have split up, a result of Tran being fed up wit his public antics with the Bajan beauty.

Several days before the 2012 MTV VMAs, Brown brandished a new neck tattoo that was rumored to represent a battered woman's face, likely Rihanna's, after his 2009 violent assault against her. On Sept. 9 Rihanna posted her latest tattoo on Instagram of a kneeling Isis with wings spread out directly under her chest and on Sept. 12 Brown also revealed a new chest tattoo that also incorporated wigs, a flying jetfighter plane.

Scherzinger, the lead singer for pop group The Pussycat Dolls, was rumored to have cut ties with her longtime boyfriend, Lewis Hamilton, a Formula One race car driver sometime last year.

The former "X Factor" judge has been romantically linked to her "Dancing with the Stars" partner Derek Hough, former "X Factor" co-host Steve Jones and rapper Drake.
