British singer Lily Allen, 39, and Stranger Things star David Harbour, 49, tied the knot in 2020 with a low-key but romantic ceremony in Las Vegas. The bride wore vintage Dior, the groom a smart navy suit, and the guests feasted on burgers from In-N-Out. Fans of the two were delighted to see them both so happy and in love. However, just over four years later, it was revealed the couple had split with friends, revealing they had been spending months living “separate lives.”

Following the announcement, rumours quickly began to swirl of infidelity on David's side, and it wasn't long before the mum-of-two was spotted on the dating app Raya. According to reports, Lily joined the site before the couple split to find David's secret profile, and when she did, it was the final nail in the coffin of their marriage. It has now been claimed that David dropped a bombshell just months after their wedding asking for an open relationship.

Earlier this month, Mail Online released a story alleging that David had been cheating on Lily for three years before their split with a costume designer. A source told the site, "David cheated on Lily. They met on a movie they did together' later adding, "they weren’t very secretive about their relationship." Now, gossip site Deux Moi has shared some insider info that claims Lily was left blindsided when David told her he needed to sleep with other women almost straight after they got married.

The source claimed: "Pre-wedding, Lily and David were totally monogamous, at least as far as she knew. Once they got married, she had to go away for work and he told her that he would need to hook up with women while she was gone because he couldn't go that long without sex. She was blindsided by this." The hosts revealed that they had heard this news before their split was announced, and it was what had led them to believe they had an open marriage. They added: "When it was revealed she was on Raya, I thought it must be a mutually open marriage. But obviously now we know it was so she could catch him in the act."

Last month, Lily took a savage swipe at her ex-husband, brutally mocking his bedroom skills during a live audience recording of her podcast. Speaking on stage at the Hackney Empire in London, the Smile singer made it clear she’s still struggling with the split. She admitted: “I am not over it. I am sort of running away. Maybe I will have a nervous breakdown.” But it was her comments about David and her other exes, including first husband Sam Cooper, that really set tongues wagging.

She went on: “I don’t think there has been one person that has been remotely interested in my pleasure,” she declared, before delivering a brutally blunt confession. The musician went on: “I have actual d**k blindness. I can’t even picture, not even my ex-husband’s or boyfriends. I can’t picture them at all. Apart from one, as I have pictures of it on my phone.”

The Express Online has contacted David and Lily's representatives for comment.
