Across Twitter, Mixers are throwing a #PerrieExposedZaynParty—and Little Mix's latest single is the invitation.

According to The Sun, the British girl group's new single, "Shout Out to My Ex," is a blunt, scathing "diss track" about Perrie Edward's former boyfriend, Zayn Malik, as well as some of the other ladies' ex-boyfriends.

The tabloid also reports that Edwards refused to warn Malik about the savage pop tune in advance, with band-mate Jesy Nelson explaining, "We don't think he deserves a warning! He'll just have to wait and see."

In one lyric from the forthcoming track, Edwards seems to claim she forced her orgasms while dating Malik, singing, "Hope she gettin' better sex / Hope she ain't fakin' it like I did, babe."

Oof.

There also appears to be a reference to the former One Direction member's famed tattoos, with another line that goes, "Guess I should say thank you / For the 'hate yous' and the tattoos / Oh baby I’m cool by the way / Ain’t sure I loved you anyway."

Ouch.

Edwards, who is now confirmed to be dating actor Luke Pasqualino, was in a relationship with Malik for four years—two of which they were engaged—before breaking up in 2015. On another "Shout Out to My Ex" lyric, the group sings, "Took four long years to call it quits / Forget that boy I'm over it."

Yikes.

But that's not all! In an alleged leaked excerpt from Little Mix's forthcoming autobiographical book, Our World, Edwards apparently reveals that Malik broke up with her via text message, writing, "It was horrible, the worst time in my life. A four-year relationship, two year engagement ended by a simple text message. Just like that. Even though things in my career were going really well, it was incredibly difficult for me."

Wowza.

Little Mix will premiere "Shout Out to My Ex" on Sunday (October 16) during the X Factor live results show, and it will be available for purchase on iTunes after. Luckily, you can listen to the track, which bears striking sonic similarities to G.R.L.'s 2014 single, "Ugly Heart," on Spotify now:
