Actor/rapper and Tv personality Nick Cannon endured a little awkward encounter with his former fiancee Selita Ebanks recently when they were seated next to each other on a U.S. talk show.

The one-time couple appeared on Thursday's (14Nov13) pre-taped episode of Katie as part of an ensemble interview with the cast of comedy reality show Real Husbands of Hollywood, and Cannon and model/actress Ebanks found themselves sitting side by side for the chat.

Co-stars Nelly and Boris Kodjoe noticed the awkward seating arrangement and began laughing as Ebanks made the first move and greeted Cannon, saying, "Hi, how are you?"

Addressing the "elephant in the room", Cannon smoothed over the situation and explained to the studio audience, "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."

Cannon, who is now married to superstar Mariah Carey, then put his arm around Ebanks and gave her a hug, before adding, "But we're cool. We're friends."

The America's Got Talent host split from former Victoria's Secret stunner Ebanks in October, 2007, seven months before he wed Carey in the Caribbean.

They both star on funnyman Kevin Hart's Real Husbands of Hollywood, but rarely share scenes together.
