But what about other members of 5SOS? Are they getting involved? Well, it seems like they are.
Michael Clifford's girlfriend Crystal Leigh has officially taken the side of #TeamLuke by inadvertently shading Arzaylea on Twitter for buying Instagram followers.
"buy stocks, not followers," she simply wrote.
It came after fans started noticing Arzaylea's major jump in followers overnight. She went from 466,000 to 475,000 in the blink of an eye.
Fans really don't miss a trick.
Of course, we can't guarantee whether or not she bought her new followers or not, but it is a little suspicious.
Fans have picked up on Crystal's shade, and are reacting on Twitter.
Arzaylea has decided to reach out to fans by posting a series of photos asking for everyone to be a little nicer to one another, and to be honest, she may be onto something.
