She sure looks like Rihanna, but the woman on Chris Brown's arm on the Fourth of July was not his ex-girlfriend.

The Ri-Ri look-alike was singer Teyana Taylor.

The two hit Sean "Diddy" Combs and Ashton Kutcher's Cîroc-sponsored White Party for Malaria No More. Inside the bash, held at a private Beverly Hills mansion, the two danced together and posed for pictures.

Brown also spent plenty of time hanging with Kanye West's on-again, off-again lady, Amber Rose...

While we didn't see anything more than friendly party interaction going on, the New York Daily News reports that Brown and Rose actually locked lips.

Brown appeared to be the center of attention, especially when Combs announced, "It's the Michael Jackson hour!" Brown, who has often been compared to the late King of Pop, busted out moves to "Rock With You," "PYT," "Thriller" and, ironically enough, "Smooth Criminal."

Speaking of Jackson, Brown told us he'd like to perform at tomorrow's memorial service, but as of Saturday night, he had no plans to participate. "They have to ask me first," he said. (P.S. We will be there, so make sure to come back here tomorrow for every detail.)

Others at the White Party—many of whom gobbled up all-you-can-eat Starbucks ice cream—were Demi Moore, Mariah Carey, Russell Brand and Shanna Moakler.
