In a shocking trailer for Dr. Oz — set to air on February 3 – Duane, 66, can be seen asking his girlfriend, Moon Angell, to be his wife.
"Moon Angell will you marry me?" he asks.
"I am a lot happier with her around," Duane tells Oz.
Duane’s daughter Lyssa Chapman admitted she’s not happy about his new love in a now-deleted string of tweets from earlier this month.
"If someone who met your family by dating your brother, tried to date your father after your step- mom died what would you do ? If you went to your mothers closet and saw she moved all her clothes and replaced them with her own, what would you do ? #ItsNotWhenOrWhyItsWho,” she wrote. "Any person who moves in on a man weeks after losing his wife, who you were supposed to be a 'friend' to, Is the lowest scum on the planet-Which for you wasn’t that far of a step down from where you were before. God will get you MARY!!!"
"Happiness is granted to all, and all I wish is happiness for my family," she said. "When a person who has ill intentions, that my mother specifically warned me about before her passing tries to enter, the war is on. The devil ALWAYS goes for the weakest link. Not today satan."
"My dad is a GROWN A** MAN," Lyssa wrote in another angry tweet. "His money. His dynasty. But you can guarantee that my name is not going down in history as a person who supported this."
Despite Duane's scandalous on-air proposal, a source close to the star exclusively told RadarOnline.com that as of now, he and Moon "are not engaged."
“Dog has a special place in his life for Moon, and he needs her companionship right now. Emotions were running high on TV and Dog spoke his mind. That’s how he operates, he says what he feels," the insider added.
As RadarOnline.com previously reported, Duane revealed that he was ready to date after struggling with the death of his longtime wife — who lost her battle to cancer on June 26, 2019.
“I’m very lonely,” he told RadarOnline.com. “Beth and I talked about death and I’d say, ‘you know Beth, I’ll never get married and I’ll never have a girlfriend again.’ She’s like ‘shut up. You will too. You need a woman beside you.'”
Still, he said no one would ever replace Beth.
“I’m the kind of guy that has to have a woman around me. There will never another Mrs. Dog,” a choked-up Duane told RadarOnline.com exclusively. “But I have to find a way to move on. I’m so lonely right now. I’m just really lonely.”
Despite having told RadarOnline.com earlier this month that he and Moon were "just friends," it appears the star has finally made their relationship public — and evidently, it’s serious.
Insiders close to the family told RadarOnline.com that Duane’s loved ones are skeptical of Moon’s intentions and claim she was “always scheming to get with Dog and the moment Beth died, she started to worm her way in on him.”
Before the holidays, Duane admitted he would be spending Christmas alone, without his children, for the first time in years. He said he had been keeping himself distracted with his work and with his new show, Dog’s Most Wanted. At the time, he did not mention his new love.
“I see myself dating again. I am a human being. I don’t ever remember being single,” he revealed. “And of course what do you do now, you go to the bars. I can’t drink. I’ll be in jail. I really can’t drink without Beth being around, because I’ll get in trouble. But I’ll probably end up dating soon.”
As RadarOnline.com readers know, Beth was diagnosed with stage 2 throat cancer in September 2017. She initially went into remission, but the disease later spread to her lungs, resulting in a stage 4 diagnosis. On June 22, 2019, while filming the show with Doug, she was hospitalized and placed in a medically-induced coma. She died four days later from complications. She was 51.
