David Harbour is “in awe” of Lily Allen

He said: “I’m in awe of her. I think she’s a remarkable, extraordinary woman and beautiful, talented, lovely, caring, but you know for some strange reason she also seems to think a lot about me so it seems to work.”

David, 46, is now stepfather to Lily’s two daughters – Ethel, nine, and Marnie, eight, whom she has with her ex-husband Sam Cooper – and also heaped praise on the youngsters.

He told Page Six: “It’s nice to be a part of their lives.”

Meanwhile, David recently revealed he has Lily’s two daughters to thank for convincing him to propose to the ‘Smile’ hitmaker.

Marnie and Ethel described David as "just some guy in our lives", and the actor was so keen to prove himself to the youngsters that he asked Lily to marry him.

He said: "We were riding around beginning of pandemic and we were riding bikes out in the country trying to figure out what we were gonna do for the next year or however long it was going to take ..

"And the little one was riding along and she was going like, 'David, dad, David, dad'. Because the D got her confused. And the older one got very upset with that, which I understand. She was like, 'He's not our dad! He's not our dad!'

"And then younger one was like, 'Well what is he? He's kind of our dad.'

She's like, 'No he's not, he's our stepdad.' And she goes, 'What is he?'

And she goes, 'He's just some guy in our lives!'"

To put a stop to any "emotional fallout" the two children might have suffered, David knew he "needed to marry" Lily.

He added: "I was like, ‘I need to marry this woman’ ... Because the emotional fallout. That's one of my favourite things I've ever been called. 'Just some guy in our lives.' Nine years old going on 35. Just some guy in our lives."

David whisked Lily away to Las Vegas in September where they acquired a marriage licence and tied the knot the following day with an Elvis impersonator officiating.
