Taylor Swift and Boyfriend Joe Alwyn Show Up Holding Hands at Jingle Ball Concert


Taylor Swift showed up to the Jingle Ball event Friday night at Madison Square Garden ... and it's the first time we've seen her hand-in-hand with her boyfriend.

Taylor and Joe Alwyn raced from their SUV to the front door, but it was enough time to see a romance marker ... hand holding.

Alwyn is a British actor and model.  They've been together since the summer, but we've never really seen them out and affectionate.
