Chris Brown and Nicole Scherzinger appeared close while partying in Los Angeles together.

The bad boy rapper and former Pussycat Dolls lead singer were amongst a star-studded line up hosting the Black Pyramid Party at LA's trendy Supperclub Venue last night. Reports state that the two celebrities, who are both thought to be in relationships with other people, were seen being tactile at the glamorous event.

"They were dancing close for a while and being all touchy-feely," a source claimed to X17online.com.

"I couldn't believe Chris was being so obvious about it!"

The publication also published exclusive photographs of the pair cosying up, where Chris was apparently seen whispering in Nicole's ear.

Chris is currently dating model Karrueche Tran who he has been linked with since late 2011, although she was not present at the venue. Similarly, 34-year-old Nicole is romancing Formula One racer Lewis Hamilton.
