*Although Selita Ebanks has been a guest star on her ex-fiance Nick Cannon’s faux reality show “Real Husbands of Hollywood,” the two came face to face again…on another television show.

Thursday’s episode of Katie Couric’s talk show featured Mariah Carey’s husband of five years alongside his co-stars Nelly and Boris Kodjoe. Cannon wound up seated next to guest Ebanks, who turned to him and said, “Hi, how are you?”

That prompted the “America’s Got Talent” host to explain. “So we’ll just clear this all up, we used to be engaged, so it’s not an awkward moment. They’re laughing that we’re sitting next to each other.”

He put his arm around the 30-year-old, adding, “But we’re cool. We’re friends.”

“Maybe we should have put you guys on different chairs,” Couric suggested.

But the former Victoria’s Secret model explained they’d been seated together because Cannon’s hot pink suit would have clashed with fellow guest Cynthia Kate McWilliams’s red dress.

Turning to Ebanks, Cannon asked, “What? You didn’t want to sit next to me?”

Ebanks’ engagement to Cannon ended in October 2007, just seven months before he married Carey, 43, in the Caribbean. As she hesitated to answer, Cannon, 33, exclaimed, “It’s about to turn into a whole different kind of talk show!”
