Chris Brown enjoyed a night out with former Pussycat Doll Nicole Scherzinger on Tuesday.

Chris Brown and Nicole Scherzinger were a part of a star-studded line up that arrived to help host the Black Pyramid Party at Supperclub in Los Angeles.

With Chris Brown, 23, fresh from a court appearance, he joined The X Factor UK judge as well as The Voice UK judge Will.i.am and singer Sean Kingston at the bash.

Chris Brown- who arrived wearing loose jeans, a plain white T-shirt, plus a hooded leather jacket – addressed the crowd with warmth and often reached out to touch fans.

As he put on an animated display inside the venue, taking to the microphone and flailing his arms in the air, his star friends smiled on as they awaited their turn to entertain.

However, while the clubbers danced and the spotlight was not on the celebrity guests, Chris Brown cosied up to Nicole Scherzinger.

The performer is currently paired up with girlfriend Karrueche Tran but she was not pictured at the venue.

Nicole Scherzinger, 34, is dating Formula One racer Lewis Hamilton, but while her beau is away in Asia for training, she got to know her industry pal a little better.

Chris Brown was seen leaning in close to the star – perhaps in an effort to be heard over the loud music – and at one point appeared to put his arm around her.

Nicole Scherzinger donned a flirty off-the shoulder with a large beanie hat on her head for the night out.

Meanwhile Chris Brown was again showing off his new darker set of locks after recently dying his hair.

He ditched his platinum blonde locks before his court hearing on Monday where it was revealed he failed a drug test.

The singer – who is currently on probation after attacking his then girlfriend Rihanna in 2009 – tested positive for marijuana in June in Virginia, where the drug is illegal, but since he claims to have smoked it in California, where he has a medicinal marijuana card. Judge Patricia Schnegg has let him off with a warning.

However, Judge Patricia Schnegg ordered a review of his progress on November 1 amid concerns about how many community service hours he has completed and allegations he has violated the terms of his travel restrictions.

She also urged him to consider how the public and his young fans perceive his actions, telling him: “You are not an average person sitting in a living room. You are not only in the public eye, but you are on probation.”

Before the hearing Rihanna, who is currently in London, tweeted Chris Brown a message of support saying: “@chrisbrown I’m praying for you and wishing u the best today (sic)” to which he responded: “thank u so much (sic).”
