Weeks after Chris Brown raised eyebrows in a very public liplock with ex Rihanna at the MTV Video Music Awards, the singer hit L.A.'ss Supperclub with another famous, pretty singer: Nicole Scherzinger.

The "Don't Wake Me Up" crooner, 23, and the former Pussycat Doll, 34, had a night out Sept. 25 at the Hollywood hotspot -- where a camera caught them dancing and kissing on the lips.

The latest snapshots probably won't go over well with Brown's current girlfriend Karrueche Tran. Dating the R&B star for nearly a year, the aspiring model, 23, was incensed when Brown and Rihanna, 24, kissed on the lips in the audience at the VMAs in L.A. Sept. 6.

Tran was "totally pissed off," a source told Us of that PDA between Brown and Rihanna, whom he assaulted in February 2009. "She felt the kiss was a public slap in the face."

"Don't Cha" singer Scherzinger, meanwhile, may also have some explaining to do: Despite a brief split in 2011, she and hunky British race car driver Lewis Hamilton, 27, have reportedly been back on for much of 2012.
