Taylor Swift’s good friend, “Royals” singer Lorde, is coming to her defense after DJ Diplo’s social media attack on his rumored girlfriend Katy Perry’s nemesis.

Perry’s boyfriend, Diplo, got involved in Perry’s feud with Swift by tweeting that a Kickstarter should be created to “get Taylor Swift a booty,” which a fan actually did create.

On Thursday, Lorde tweeted “@diplo should we do something about your tiny penis while we're at it hm,” which she has since deleted but was retweeted over 16,000 times.

It was revealed that Swift and Perry had major issues when Swift explained her 1989 song “Bad Blood,” saying a fellow female singer – believed to be Perry – tried to “sabotage” her.

Perry then indirectly responded on Twitter, writing, “Watch out for the Regina George in sheep's clothing...”

Swift hasn’t responded to Diplo’s diss but she has been busy with another petty back and forth exchange with Spotify.
