With lyrics like "You just want attention, you don't want my heart, Maybe you just hate the thought of me with someone new. Yeah, you just want attention, I knew from the start. You're just making sure I'm never gettin' over you," fans are sure it's about Bella Thorne.
In case you forgot, there was major scandal when he and Bella were spotted kissing and holding hands last year while Bella was still dating Tyler Posey. It resulted in Charlie sending Tyler like five apologies on Twitter... Very awkward.
Fans have made it pretty obvi that they can hear Charlie louddd and clear on Twitter.
Charlie hasn't said who the song is about, and we may never know. But hey, it's still a tune.
