Mariah Carey kicked off the first show of her "All I Want for Christmas Is You" tour at New York City's Bacon Theater on Monday, December 5. The chemistry between Mariah and her new toy boy Bryan Tanaka was undeniable during the show.

Mariah was caught checking Bryan out for several times mid-performance. The pair also shared a moment gazing into each other's eyes.

Thanks to all who came to the @beacontheatre show tonight. I don����¯�¿�½������¢������¯������¿������½������¯������¿������½t have words. Thanks for sharing such a special night with me. Hope you enjoyed it as much as I did! Feeling very grateful right now.

Mariah wore a red, cleavage-baring Nutcracker costume. At one point, she was lifted up by some male dancers while Bryan was holding her hand.

Later that night, Mariah and Bryan went for a late dinner date at a midtown restaurant right across the street from the theater. The "We Belong Together" songstress flaunted her curves in a black peek-a-boo dress paired with fishnet stockings and strappy heels. Her boyfriend, meanwhile, rocked a black leather jacket, a red tee, jeans and sneakers.

Meanwhile on Tuesday night, Mariah stepped out solo in a white bra top paired with a red cardigan, black pants and boots to flip on the lights at the Empire State Building.
