Katie Couric's Fiancé John Molner, Barbara Walters Surprise Host On-Air (VIDEO)

Katie Couric was stunned when her fiancé John Molner and Barbara Walters came by for a surprise visit.

Couric's daytime show was back on Monday for its second season, and the host shared the exciting news of her engagement with viewers. She and Molner got engaged in the Hamptons over Labor Day weekend.

On her first day back, Couric was prepared to take questions from audience members about her engagement when Barbara Walters came out from backstage, shouting, "I have a question!"

Later, Walters asked when everyone would get to meet Molner. Couric said "one day, but hopefully not on the show because he doesn't want to do that." Little did she know Molner was backstage waiting to surprise her with roses. Watch her reaction in the video above.

"I didn't know he was showing up," she later told "Good Morning America." "So it was kind of cute."
