A clear sign you've become romantic kryptonite: when even a former Pussycat Doll doesn't want to be associated with you.
In the blurry pics snapped Tuesday night at Supperclub in Los Angeles, Chris, 23, and Nicole, 34, can be seen having what looks like a cozy tête-à-tête, with one eyewitness claiming it went beyond mere chitchat.
"They were dancing close for a while and being all touchy-feely, and finally Chris leaned into her," a source alleges to X17. "She put her head on his shoulder and they started kissing! I couldn't believe Chris was being so obvious about it!"
Since it's pretty hard to discern what's happening from the blobby, head-like shapes in the images, we'll let Scherzinger explain.
"There is absolutely no truth to the ridiculous story," Nicole's rep fumes to 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 rep concurs, telling Wonderwall, "No story here. They were not kissing. They are friends, and have been for years. They were talking at a club that was playing loud music."
Brown, for his part, is still coupled up with Karrueche Tran, who reportedly wasn't thrilled that he kissed onetime girlfriend-turned-assault victim Rihanna at the MTV Video Music Awards earlier this month (we're right there with you, Karrueche, if for very different reasons). Scherzinger is dating British race car driver Lewis Hamilton.
