Charlie Puth was performing in Dallas on Friday night, when he suddenly said “F*ck you, Justin Bieber,” in the middle of singing “We Don’t Talk Anymore.” His comment was followed by cheers from the audience. The song features Justin Bieber’s ex, Selena Gomez.

Later that night, Charlie Puth took to Twitter, issuing a since-deleted apology to Justin Bieber.

“Hey everyone. I feel like I need to clear something up,” the “See You Again” singer wrote in three consecutive tweets. “What I said at the concert last night about Justin was meant to be a joke. However.. The way it was said mid song did not sound like one. I am a massive @JustinBieber fan and I have nothing but great things to say about him and his music always.”

As most people know, Justin Bieber and Selena Gomez were an “It” couple for nearly three years. The two have since broken up for good.

What do you suppose Charlie Puth meant when he made his comment about Justin Bieber during his Dallas concert? Was he implying that he “had” Selena Gomez–as in on his track–and Justin Bieber no longer had the “Come and Get It” singer?

The comment was odd, but the fact that Charlie Puth deleted his apology is even stranger.

It will be interesting to learn if this situation gets explained via social media or otherwise, in the next few days.
