Joe Alwyn is in L.A. while his ex, Taylor Swift, and her current boyfriend, Travis Kelce are in town … and it seems there’s a common connection in one Emma Stone.

The British actor surfaced Friday near a coffee shop in Studio City, where he appeared to be on his own and minding his business — but by the same token, he wasn’t really going incognito … while JA was rocking a ball cap and shades, he removed both.

What this seems to mean … Joe wasn’t shy about having his mug out there, and he didn’t appear to mind being photographed either. The dude’s just out there doing his thing.

This is interesting for a few different reasons — one, he’s technically on Taylor’s turf here, and not just that … but she’s out here in L.A. right now with none other than TK — who’s been a man about town as well. Of course, if these 2 were to run into each other … awk.

Taylor and Joe were together for 6 years before they split up in 2023 — and in the aftermath of her getting with Travis … she’s got a new album coming out that seems primed to take JA to task, at least that’s what the Swifties seem to think anyway.

In any case … Joe doesn’t seem to care if he crosses paths with T-Swift and Travis — ’cause, frankly, he actually has a reason to be in town, and it’s work-related.

If you didn’t hear, Emma Stone is gonna be in this new movie with the same director who just helped win her an Oscar … and Joe’s gonna be in it too. In fact, this will mark the second time that Joe has worked with ES on a Yourgos Lanthimos movie … they already did “The Favourite” together a few years back, and YL is reteaming with these two again for his latest.

Interestingly enough … Taylor and Emma have a good friendship as it is, and now — Emma’s slated to work with her ex, who’s now cruising around L.A. as Tay Tay is on a lil’ break.
