Diplo dealt Taylor Swift a low (but semi-funny) blow last night when he tweeted, "someone should make a kickstarter to get taylor swift a booty," but things quickly escalated when Lorde got involved in the Twitter battle. Coming to her bestie's defense, the New Zealand-born singer tweeted, "Should we do something about your tiny penis while we're at it hm," and a number of fans re-tweeted her message to the DJ. Real mature, guys!

As you may know, Diplo, 36, is currently dating Katy Perry, who famously feuded with Swift earlier this year on social media. And let's not forget that T. Swizzle penned "Bad Blood" about their frenemy status. Back in September Katy tweeted, "Watch out for the Regina George in sheep's clothing," and in an interview with Rolling Stone, Taylor hinted that she had some big beef with Katy.

"For years, I was never sure if we were friends or not," Taylor told the mag. "She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?' She did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy! It had to do with business. She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me. And I'm surprisingly non-confrontational you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it." Meow!

But here's what's even more interesting -- Lorde and Diplo are friends (or at least they used to be), so is this whole thing just getting hyped up by the press? Diplo remixed Lorde's track "Tennis Court" for the new Hunger Games soundtrack, and back in April she posted a photo of the two and wrote, "me and bud last week at coachella." But how does she know that he has a wee wang? We don't even WANT to know...

And we're not sure if Katy put Diplo up to this, but there has to be a better way to handle it...
