In photos obtained by TMZ, the 13 Reasons Why star can be seen kissing and holding hands with the British artist while out and about in Greenwich Village.
When asked about the pair's relationship, reps for both Smith, 25 and Flynn, 23 were unable to comment.
Sam was most recently romantically linked to model Jay Camilleri in 2016 and prior to that he dated model Jonathan Zeizel in 2014 who is said to be the inspo behind his Grammy winning banger "Stay With Me".
Now it looks like he's done with the models and onto actors, and Brandon Flynn is defs a great place to start.
