Taylor Swift‘s ex-boo Joe Alwyn is at least tryin’ to shake it off … surfacing in public for the first time since news broke of their split.

The actor was spotted Thursday in central London … nearly 2 weeks after the world found out their 6-year relationship was over. He was taking some calls while strolling and, honestly, the dude looks like he ain’t getting much sleep.

Hard to say if the frazzled look is related to life A.T. (after Taylor) — he could be upset about the breakup, or he could just be enjoying his new life as a single guy.

As you know, their split rocked the world of Swifties, but it was reportedly an “amicable” ending. Of course, that isn’t always how things go for TS — with her often taking the drama of a nasty breakup and turning it into a hit song.

Following the split, we’ve seen Taylor out a few times in NYC, even grabbing dinner with her pal Jack Antonoff … and putting in some work at a recording studio — all as she’s neck-deep in her Eras Tour.

If you compare their public outings … Taylor at least seems to be handling the life change a little better than Joe.

Word of advice to him — stay out of coffee shops, those Taylor tunes will hit differently now.
