Richard Osman found "the one" during the pandemic, 14 years after his divorce.
The TV presenter and author, 51, fell head over heels for Doctor Who star Ingrid Oliver after the pair went from being just friends to something more.
He gushed on the Christmas Day edition of Desert Island Discs, he said: "I’m happy with myself, I’ve got these beautiful kids, I’ve met the woman who I’m going to be with for the rest of my life.
"'That thing of competition and ambition, you soon realise that rocket fuel disappears and it’s about happiness and my kids bring me happiness and Ingrid brings me happiness."
The pair have taken their relationship to the next level and Ingrid, 44, has moved into Richard's home in south-west London.
The Would I Lie To You panelist has been with a string of women since his marriage broke down, but none had lasted the test of time.
Ingrid is best known for her role as Petronella Osgood in Doctor Who and has previously featured alongside her new boyfriend on his show Richard Osman's House of Games.
She is the daughter of Conservative MP Jo Gideon and starred in her BBC sketch Watson & Oliver.
Upping the romance levels further, Richard very smoothly dedicated a classic Erasure track A Little Respect to the actress.
Richard and Ingrid's love blossomed during the first lockdown, with Richard telling friends at a dinner party after restrictions had lifted that "she is the one".
He and his now ex tied the knot in the late 1990s and divorced in 2007.
The pair share two grown up children, Ruby and Sonny.
In an interview with The Times, Richard said that he wanted to spend as much time with his children as possible after his dad left home when Richard was just 10 years old.
"When my partnership broke up, I did think, 'Oh God, this is going to be awful'.
"I've seen my kids nonstop. It was quickly worked out it wasn't going to be the same, which is an extraordinary relief,” he said. “They know I love them and I tell them nonstop, which bores them rigid. But I never got told that."
In 2018 he dated jazz singer Sumudu Jayatilaka but their relationship was short lived.
When he was asked about the break up, he refused to speak about it but when he was whether the romance in his book was autobiographical he said: "“I’d rather not go into all of that.
"We’re not together, so I’d rather not upset her at all."
In an interview before he met Ingrid, he said that he enjoyed being single.
