Last week, we reported about the unexpected Twitter feud between Calvin Harris and Zayn Malik.
At first, it seemed like a simple case of a loving (and possibly over-protective) boyfriend sticking up for his girl.
Now, it's beginning to look like Calvin just gets off on picking fights with random celebs on social media.
The latest beef began when Taylor liked a Tumblr post comparing her fan interactions with those of other celebs:
Avril fans (which apparently still exist) were not happy and they began tweeting trash-talk at Taylor.
Avril herself attempted to clear the air, tweeting, "Comparison is judging and judging a person does not define who they are it defines who you are. We all Love our fans...So let's keep it all about the love and stay positive."
Apparently, those are fightin' words in Calvin's world, because minutes later, he tweeted to Avril:
“She didn’t judge you she doesn’t judge anyone! She was only having fun with her fans, not trying to compare you.”
Whoa, dude. Your bro-rage is showing.
Several media outlets have pointed out that Calvin has a long history of social media tantrums that includes an ugly verbal attack on his ex-girlfriend Rita Ora.
Others gently reminded Harris that Avril has Lyme disease and maybe isn't the best target for his furor.
For months now, Swift fans have been vocal about their hopes that Calvin is "the one," but they can't be too happy about this seething douche side that he's now showing the world.
