David Harbour goes solo on red carpet after ‘affair’ during Lily Allen marriage
The couple split last year after four years of marriage.
David Harbour appeared downcast at CinemaCon 2025 after claims the Stranger Things star had an affair during his marriage to Lily Allen.
The Smile singer 39, and Violent Night actor, 49, split last year after tying the knot in 2020.
It has since emerged that David was allegedly in a secret relationship behind Lily’s back for three years with a costume designer.
The actor appeared on the red carpet at this year’s CinemaCon, posing for photos with a muted expression.
He wore grey trousers and a black shirt for the occasion, standing alongside Florence Pugh for the event celebrating Disney’s upcoming slate of films.
The actors are both set to appear in the upcoming Marvel film Thunderbolts based on the comic books of the same name in which a group of antiheroes are forced to work together after being caught in a deadly trap.

Shostakov is the super soldier counterpart to Captain America and acts as a father figure to Belova.
The first five minutes of the film were shown at CinemaCon, with Florence introducing the audiences to ‘our new team of glorious misfits’ alongside David and fellow cast members Julia Louis-Dreyfus, Hannah John-Kamen, and Wyatt Russell.
CinemaCon marks David’s first red carpet appearance after news of his alleged affair was reported.
It’s believed David and Lily parted ways in December, with Lily subsequently spotted on the celebrity dating app Raya in December 2024.

‘Lily was looking for women that were on Raya and cross-referencing them with women David follows on Instagram to try to figure out who he was seeing. She was doing her Wagatha thing,’ a source told Mail On Sunday.
A source later told the publication that the Hellboy star had embarked on a secret relationship for the majority of his marriage.
An eyewitness who claims to have seen Harbour interact with the costume designer on the set of a movie told MailOnline: ‘David cheated on Lily.’
‘They met on a movie they did together,’ they added: ‘They weren’t very secretive about their relationship.’

Last month, David was spotted on a date with Ellie Fallon, an aspiring model 22 years his junior.
Musician Lily has recently unveiled she has undergone a boob job and hopes to be sending nude photos in the future following the split.
Speaking to close friend and co-host Miquita Oliver on their Miss Me? podcast this week, Lily stated: ‘How do I feel about ageing? Well, I just got some additions to the family – don’t know if you’d noticed?’
Lily continued: ‘They look really incredible when I take my top off, and my bra off, but there’s definitely a contrast in age between my breasts and my face.

‘I don’t think there has been one person that has been remotely interested in my pleasure,’ she declared during a live recording of Miss Me? in London.
‘I have actual d**k blindness.’
Lily continued: ‘I can’t even picture, not even my ex-husband’s or boyfriend’s. I can’t picture them at all. Apart from one, as I have pictures of it on my phone.’
Metro has contacted representatives for David Harbour and Lily Allen for comment.
