Romance rumors have swirled in recent months, as Carey and Tanaka have been spotted out on date nights in Los Angeles. The dancer also appears in Carey’s new reality series, Mariah’s World, which premiered on Sunday.

Following the show’s premiere, the duo further fueled the romance rumors at a viewing party for the show at Catch restaurant in New York City’s Meatpacking District. They looked like ever the love birds as they posed for photos at the event.

“I’ve always had a thing for Mariah. I love her so much,” Tanaka told E! News. “Just make sure you tune in to the show and you’ll see kind of how everything happens.”
