Charlie “A Scourge” Puth yelled “Fuck you, Justin Bieber!” while performing his song “We Don’t Talk Anymore,” which features Bieber’s ex Selena Gomez on the studio version, during his Dallas concert on Friday, Us Weekly reports. Check out footage of the incident in question below.

Puth later apologized on Twitter, saying he was just joking. But apparently he wasn’t feeling too apologetic, because he deleted the tweets shortly thereafter.

So, I guess the big question here is: #teamputh or #teambieber?
