Chris Brown is close friends with Nicole Scherzinger's boyfriend Lewis Hamilton.

The R'n'B singer has laughed off reports he hooked up with the gorgeous 'X Factor' UK judge in a Los Angeles club on Tuesday night (25.09.12) and insisted he is close with both Nicole and Lewis and the pair looked cosy because they were simply talking over the loud music.

A spokesperson for Chris said: ''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.''

Nicole was spotted catching up with Chris and other close pals including and singer Sean Kingston at the Supperclub on Hollywood Boulevard earlier this week, where the 'Without You' singer was hosting the Black Pyramid party.

Chris was previously seen hanging out with British Formula One racer Lewis in Cannes in July without Nicole.

The McLaren driver, who is currently training in Asia, refers to Chris as his ''homie'' on his twitter page and the pair also share multiple other mutual friends including rappers Ludacris and Swizz Beatz.

Meanwhile Chris has been dating Karrueche Tran for over a year.

The model supported him following his court appearance on Monday (24.09.12) where it was revealed he tested positive for marijuana in Virginia recently, violating his probation in relation to his assault on Rihanna in 2009.
