Lily Allen has been married to the 'Stranger Things' star since 2020

Insiders claim the pair are having marriage issues and have barely seen one another in the last three months.

The singer has been focusing on her acting career in London, and Harbour has been working in New York.

A source told The Sun that there has been no sign of David in recent weeks.

They shared, "When she went back to the US with them, there was no sign of David."

"Lily and David have barely been together for the past three months and have been living separate lives.

"When she was in London for the Pillowman, David was spotted at one performance in July before Lily was left by herself. In her downtime, Lily would be with mates in London or her kids."

News of their marriage problems come after Allen unfollowed Harbour on Instagram. Fans were quick to notice and expressed concerns about the pair's relationship.

The 'Not Fair' singer married Harbour in Las Vegas in 2020. They were joined by Allen's two daughters, Marnie and Ethel, who are both incredibly close to Harbour.

Allen marked their three-year anniversary in September by sharing a photo from their wedding day.

Alongside the candid shot of her laughing with Harbour, Allen wrote, "3 years with this guy, 2nd best decision I ever made. 1st was that dress."

Harbour and Allen have been together since 2019 after meeting on celebrity dating app Raya.

Allen was previously married to Sam Cooper for four years, but the pair ended their marriage in 2015.
