In her current single, “Touch My Body,” Mariah Carey jokes about a secret, romantic rendezvous. But is the pop singer having a real one?

Carey’s rep denied last week that the singer and actor Nick Cannon are dating, but the duo looked cozy at a party Monday night in Las Vegas.

After landing by private jet, the pair headed straight to Privé Las Vegas at Planet Hollywood, where Cannon, who stars in one of Carey’s videos, was scheduled to deejay. Making their way to a VIP table, the pop diva whispered into Cannon’s ear just before he took to the turntables.

With her BFF Da Brat by her side, Carey – wearing over-sized sunglasses and dressed in all-black – danced to the music as she sipped water and white wine, then feasted on hamburgers, chicken fingers and French fries. And for dessert? A chocolate cake for Da Brat, who was celebrating her 34th birthday.

“We have a very special person in the house tonight,” Cannon called out on the microphone. “Happy birthday, Brat.”

He also seemed to give Carey a “secret” shout-out. Carey stood up on the back of the booth and raised her wine glass when Cannon put on Jay-Z’s “Public Service Announcement” and sang along with the lyrics, “I got the hottest chick in the game.”
