This morning on SiriusXM, Maria Menounos‘ long-term partner Keven Undergaro proposed to her live, and she was stunned.

She was on Howard Stern’s show promoting her new book, The EveryGirl’s Guide to Cooking when the host asked her if she had ever thought about dating anybody outside of her nearly two decade long relationship.

“At the end of the day, Keven and I are partners in life,” said Menounos.

Then, Stern invited Undergaro into the studio.

“It was so emotional to hear you say everything, because listening to everything you said back there, back when we were in the green room talking about what you’ve been through, I’ve been through too… when we wanted to be together, we couldn’t because people didn’t want us together, and then it was literally like the last 17 or 18 years of us fighting together, and me defending her as best I could,” Undergaro said.It reminds me just how much I do love you, and although I said this isn’t a proposal, I want to ask you something… Would you make me the happiest man on earth and would you marry me?”

Menounos was in such disbelief that she didn’t respond at first, even as Undergaro got down on one knee.

“This I won’t joke about,” Undergaro promised her. “I love you so much and this show’s meant so much to both of us… Why not make it official now? Will you, honey? Will you accept?”

Menounos was crying when she finally said, “Yes, yes, yes! Oh my gosh! Of course! I can’t believe this is happening! Oh my god! This isn’t happening right now! Honey, are you serious right now? Oh my god! I love it. Oh my god, it’s amazing. Thank you. Oh my god.”

Stern then brought in Menounos’ parents, who were celebrating their 41-year anniversary. Menounos initially was thrown out by her father when she started dating Undergaro, because he was Italian-American and Menounos’ family was Greek Orthodox. The couple lived in a basement in Boston before moving in L.A. to start her career. They have since reconciled and her father has apologized to Undergaro.

They pair have been dating for almost 19 years. They work together on their joint AfterBuzz TV online network.
