Rihanna — who after months of speculation admitted she is back together with Chris Brown — showed appreciation for her man’s singing talent while partying with girlfriends at Kiss & Fly in the Meatpacking District on Wednesday night. “Rihanna jumped on the couch to dance when DJ Camilo played ‘Don’t Wake Me Up’ by Chris Brown,” says a source. Our spy added of the “Diamonds” singer and her posse: “Rihanna seemed to be in good spirits. She and her group came around 12:30 a.m. and didn’t leave till 3:15 a.m. They were sipping on Jack and Cokes, dancing and laughing.” After being spotted continually with bad boy Brown, Rihanna revealed in the latest issue of Rolling Stone, “We know exactly what we have now, and we don’t want to lose that.” But she added of Brown, who infamously assaulted her the night before the Grammys in 2009, “He doesn’t have the luxury of [bleeping] up again. That’s just not an option.”
