Scherzinger spotted kissing Brown?
They appeared to be caught kissing, reports The Sun.
The 'X Factor' judge, who is in a relationship with F1 ace Lewis Hamilton, was seen with Rihanna's former beau at a club Tuesday.
They danced together and spent much of the evening side by side talking.
According to reports, the pair had been kissing, but Scherzinger has denied it through her spokesperson.
"There is absolutely no truth to the ridiculous story regarding Nicole and Chris Brown. The photos are of old friends who were trying to talk at a very loud club. They were not kissing," said her spokesperson.
Scherzinger has been in an on-off relationship with Hamilton since 2010.
Meanwhile, Brown is reportedly getting close to former love Rihanna. They had split after he admitted to assaulting her in 2009.
