In the clip, Carey finds herself at a crossroads while planning a wedding to now ex-fiance, James Packer. "Are you really gonna marry this guy?" Tanaka asks Carey.
"Why?" she replies.
Tanaka responds by assuring Carey that he just wants her to be "happy," but the superstar has an admission of her own. The GRAMMY winner confesses that she "doesn't even know" if she's ready to tie the knot.
"No matter what happens, I'm going to follow my heart," Carey declares to the camera just ahead of a scene where she and Tanaka share a kiss on the beach.
A lot has obviously changed since Carey filmed those scenes for her reality show. Carey split with Packer and is now in a "proper relationship" with 33-year-old Tanaka, a source confirmed to ET.
"She's really into Bryan. He's with her 24/7," a source revealed, adding that Tanaka is a "nice guy."
Tanaka hit the stage with Carey on Saturday during her performance on Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest that was riddled with technical difficulties. Prior to the show, Carey and Tanaka jetted off for a "romantic" getaway in Aspen, where she enjoyed time in the snow, and posed for a sexy hot tub snapshot.
