Chris and Amber Sitting In A Tree

Chris Brown and Amber Rose locked lips at the July 4 White Party thrown by Sean (Diddy) Combs and Ashton Kutcher in Beverly Hills, spies tell the Daily News.

Brown, 20, arrived at the party with singer Teyana Taylor, an 18-year-old Rihanna look-alike, but is said to have hooked up quickly with Rose.

"Diddy announced the deejay would do a tribute to Michael Jackson," said a guest. "Chris did an amazing impression of Michael's moonwalk. It wasn't long before he was dancing with Amber."
Later, as the party wound down, the pair nestled on a couch in the backyard of the Beverly Hills mansion. "They were holding hands and making out in the shadows," said a witness. "She had her hand on his leg."

Taylor is said to have been irked by the amount of time Brown spent with Rose, but still accompanied him to an after-party at the club Guys.

There, Brown again got upclose and personal with Rose, who is 26.
"They were kissing on the dance floor in front of Teyana," said a witness. "But he and Amber left separately."

Some wondered whether the flagrant display was a defiant message both to Rihanna and West. Rihanna dumped Brown, who last month pleaded guilty to assaulting the Grammy winner.
West, who has said he was "devastated" by Brown's attack on a woman who was like "my little sister," has run hot and cold on Rose lately. Although he reportedly broke up with her last month, they came together at last week's BET Awards show.
