Last week, Kim Kardashian unexpectedly slammed Taylor Swift during an interview with GQ.

Relations between Taylor and Kim’s husband, Kanye West, had been tense for quite some time, but even so, Kim’s intervention into the feud was unexpected.

If you’re married to Kanye, you can’t go involving yourself every time he beefs with another celebrity, but apparently Kim felt that Taylor was an enemy worth fighting.

Asked about Taylor’s comments about Kanye’s lyrics, Kim basically called Swift out as a liar, claiming that the singer “totally knew” about potentially offensive lines and even approved them prior to the release of West’s latest album.

Taylor has yet to comment on the situation, but her reps diplomatically fired back, issuing a statement in which they politely claimed that “much of what Kim is saying is incorrect.”

Of course, as we know from Taylor’s ongoing feud with Katy Perry, the girl’s not one to back down from a fight.

And like all great warriors, Taylor enjoys complete command of her favorite weapon – the diss track.

Once the territory of rappers and Carly Simon, the diss track has been co-opted by Taylor as her preferred method of handling beefs with everyone from Perry to John Mayer.

Now, it seems Kim is nest on Taylor’s hit list:

“Taylor’s already been inspired to write some harsh lyrics [about Kim],” a source tells Hollywood Life. “Kim messed with the wrong woman.”

We hope this track eventually sees the light of day, but we wouldn’t be surprised if Taylor holds off, as this time she might be biting off more than she can chew.

We doubt that Kim would ever return fire in song form (though it would be hilarious if she tried), but she’s married to the king of petty feuds.

“He’s planning an epic takedown of Taylor on his upcoming tour,” says one insider “He’s going to slam her nightly.”

This whole thing might a lot worse before it gets better.

Frankly, we can’t wait.
