The 25-year-old actor was in Montreal, Canada for Taylor Swift's latest stop on her 1989 world tour. In fact, a lot of the X-Men: Apocalypse cast was there -- James McAvoy, Sophie Turner, and producer Simon Kinberg -- and from the look of things, he got pretty into it!
Cameras even caught Hoult singing along to Swift's hit "We Are Never Ever Getting Back Together," and we've gotta say, someone should make an appearance on Lip Sync Battle!
Unfortunately, Swift's known BFF Jennifer Lawrence did not join her cast mates for the concert fun. She could be trying to avoid her ex Hoult (don't date your superhero movie co-stars, y'all) or it’s also possible she had an early shoot.
Lawrence was spotted earlier in the week arriving in Montreal with co-star Rose Byrne.
