Paul Mescal On Date With Gracie Abrams in London

We have a possible new couple alert from across the pond … because we just got photos of Paul Mescal on a date with Gracie Abrams.

Check it out … the Irish star and the “us.” singer are sitting at a tiny table together inside a packed restaurant for what appears to be a dinner date.

Folks who were there say Paul and Gracie broke bread at BRAT Restaurant in London, where they ordered a bunch of small sharing plates.

The outing comes on the heels of Gracie releasing her second album, “The Secret of Us” … which features a collab with Taylor Swift — the one they spent all night writing at Tay Tay’s NYC apartment when TS put out a kitchen fire.

Paul’s already cozied up to Ayo Edebiri and Natalie Portman this year … but both instances turned out to be the friendly type.
