The pop star and actor made it official with a PDA in NYC

Their romance was allegedly rumoured over the summer, but it sounded so utterly random that we found it hard to believe.

However, it looks like pop star Lily Allen and American actor David Harbour (best known for his role as Jim Hopper in 'Stranger Things') are really a couple.

The pair were papped in New York the other day as they walked through Chinatown, and they were not shy about their PDAs.

Harbour hosted SNL on Saturday night, and apparently the LDNer was in the audience to support him. Allen split from her boyfriend of three years, Meridian Dan, last Christmas. Harbour's most recent relationship was with actress Alison Sudol, which ended earlier this year.

Allen confirmed the relationship on her Instagram story, sharing a screengrab of Harbour's bicep from SNL and captioning it 'mine'.

There's a multitude of photos doing the rounds on social media that show them pretty loved-up, some of which you can see below... as well as the reaction to their relationship.

G'luck to them, etc...
