Nicole Scherzinger and Lewis Hamilton have gone their separate ways and tried to get over their recent break up after the couple split earlier this month.
Lewis, 28, said his world had been "turned upside down" after splitting from his girlfriend of five years.
The Formula One world champion was spotted partying at the Playboy Mansion in Los Angeles, mingling with rappers Snoop Dogg and Chris Brown, Rihanna's ex-boyfriend who had attended his court appearance that same day for an alleged hit-and-run incident.

Lewis opted for a black leather jacket, matching black T-Shirt, grey jeans, black trainers and a silver chain with cross as he attended the eighth annual BTE All-Star Celebrity Kickoff Party at the infamous mansion.
Nicole, meanwhile, has been busy filming for the hit TV series The X Factor in London. She was said to be "heartbroken and completely devastated" after the break-up but seems to be holding up.
"From my HEART-Thanku so much to all my fans 4 sending ur words of wisdom & faith, love & inspiration right now..God Bless u, I love u xo," tweeted Nicole, showing her appreciation for her fans.
During an audition where a hopeful X Factor contestant sang about heartbreak and the end of a relationship, Nicole said, "It pulled on my heartstrings. It sucks doesn't it? Really sucks."
Nicole recently celebrated her 35th birthday where she was showered with gifts from her fans, contestants and previous X Factor singers including Jahmene Douglas.
Nicole and Lewis had briefly split in January 2012 but ended their relationship once again earlier this month. It was speculated that the couple were heading towards marriage after their long-term relationship.
"We've been together for five years, which is quite a milestone really," said Lewis. "Hopefully in the near future, maybe before we get to six years," he said, when quizzed over when he would pop the question.
