Look Back on David Harbour and Lily Allen’s Relationship Timeline

David Harbour and Lily Allen have come a long way since meeting on a dating app.

The duo first sparked romance speculation in August 2019 after they attended a play together in London. Two months later, they made their red carpet debut at a Skin Cancer Foundation Event.

Allen and Harbour tied the knot in Las Vegas after they were inspired by a comment made by Allen’s daughters, Ethel and Marnie, whom she shares with ex-husband Sam Cooper.

“We were riding around at the beginning of the [coronavirus] pandemic — she has two kids, these beautiful daughters, 8 and 9 — 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,” the Stranger Things star recalled during a June 2021 appearance on Jimmy Kimmel Live! “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, and she was like, ‘He’s not our dad! He’s not our dad!’”

He continued: “And the younger one was like, ‘Well, what is he? He’s kind of our dad.’ She’s like, ‘No, he’s not.’ ‘He’s kind of our stepdad.’ ‘No, he’s not,” he continued. “And she goes, ‘What is he?’ And she goes, ‘He’s just some guy in our lives!’ … I was like, ‘I need to marry this woman.’”
