Chris Brown was "making out" with Amber Rose - while his date looked on. The "Run It" star locked lips with the model - the ex-girlfriend of Kanye West - at P. Diddy's White Party in Beverly Hills on Saturday night, despite arriving at the bash with 18-year-old singer Teyana Taylor.

A source told the New York Daily News newspaper: "Diddy announced the DJ would be performing a tribute to Michael Jackson. Chris did an amazing impression of Michael's moonwalk. It wasn't long before he was dancing with Amber.

Chris Brown pleaded guilty to felony assault for the February beating of ex-girlfriend Rihanna in a Los Angeles court room on Monday. The star won't be seeing any jail time, however. He also won't be seeing much of Rihanna. The judge has ordered Brown to stay 50 yards away from the "Umbrella" singer.

The 50-yard deal becomes 10 yards, however, if they are both present at the same event. Also included in the plea deal are 180 days of community service, such as trash removal in his home state of Virginia. He'll also have to attend two weeks of domestic violence counseling.

Rihanna and her new boyfriend are inseparable. The "Umbrella" singer - who is rumored to have been dating Aubrey 'Drake' Graham for two months - was seen canoodling with the upcoming Canadian rapper at a premiere after-party for new movie "Year One" at New York's Empire Hotel on Monday.

Rihanna - who was allegedly assaulted by ex-boyfriend Chris Brown - barely left the 22-year-old's side as they flirted and frolicked at the bash before heading to the VIP section of nearby nightclub Greenhouse.

Rihanna is pursuing a basketball star. The "Umbrella" singer was in the crowd to see the Orlando Magic play Los Angeles Lakers last week - as was her ex-lover Chris Brown - and friends claim she watched the game because she has a crush on Orlando player Rashard Lewis.

A source said: "Rihanna is trying to get to know Rashard. She's digging on him, and she hopes the feeling is mutual."
