Mariah Carey and Bryan Tanaka may be in a full-fledged romance now, but the singer's reality show, Mariah's World, is giving viewers a look into the moment it all started!

In a new promo for this week's episode of the E! docuseries, Tanaka confides in fellow dancer G. Madison that he's "catching some hard feelings" for Carey.

"I can't believe I'm saying this right now," Tanaka says in the clip. "I'm catching some hard feelings [for] Miss Mariah."

"I don't know if I'm trippin', but it's been kind of going a little nuts lately," he confesses. "I feel like our chemistry is not just professional. There's great chemistry professionally, but when we talk, it feels like there's a connection that is more than what we've had for the past 10 years."

"I wouldn't cross that line if it didn't feel the way it does," he adds. "I know it's a complicated situation… That's where I'm trippin', like she's engaged [to James Packer], so maybe I'm really just trippin'."

Later, Tanaka makes his love for Carey -- or her butt, rather -- known during the group's karaoke party, where the singer's alter-ego, Bianca Storm, arrives in a skin-tight black ensemble.

"Somebody had an idea that we should -- well, I don't have to do it because I am me -- but they were all gonna dress up as me, Mariah," Carey says to the camera. "But I have a little surprise."

Carey then makes her way down the stars, where the group (including Tanaka) goes absolutely crazy.

"Bianca's a** looks hella fierce," Tanaka says. "Look at that! Bianca's a** is perfection right now and she's complaining. I don't know why she's complaining but it's perfection right now."

"Were you talking about my...look at him!" Carey teases back.
