13 November 2014: Ok so the spat between Taylor Swift and Katy Perry just hotted up! Katy's man Diplo just blasted Taylor's bottom. The DJ appealed to his fans on Twitter and posted: 'Someone should make a kickstarter to get taylor swift a booty (sic).'
Oh, no, he di'nt. (Spoiler: Yes he did, and some)
Diplo didn't stop there he added: 'are taylor swift fans called the swift boat veterans? (sic),' no we don't get it either.
Katy's man then retweeted a link to a Fundly account entitled Get Taylor Swift A Booty started by a fan. The description of the account read: 'It said: "Taylor Swift Still Needs Your Help! Any true supporter of TSWIFT would definitely not pass up this opportunity to improve her posterior! THIS IS A JOKE (sic)"
At the time of writing 28 supporters had donated $45. Such baffoons.
Taylor sparked the feud with K-Pez after saying she was 'straight up enemies' with someone she thought had been a friend in an interview with Rolling Stone magazine. Apparently Katy stole some dancers from Taylor's tour to go on her own. Or it could be because they've both dated John Mayer. Who knows.
Katy appeared to reply to Taylor's comments by tweeting: 'Watch out for the Regina George in sheep's clothing... (sic).'
Come on guys, can't we all just get along?
