Justin Bieber is firing back at boy band 5 Seconds of Summer after the band’s drummer Michael Clifford took shots at the singer in the new Rolling Stone magazine.

The drummer told the publication that Bieber “hates” the Australian band, and added that the pop star “had his own album on loop for, like, two or three hours” at his AMAs after-party.

Even if that is true — we don’t blame him. We love Purpose!

The Biebs responded to the jabs by tweeting, “@Michael5SOS Sorry guy, [sic] don't hate you. Don't even know u. And u sure u came to our party because my album wasn't on loop? Strange.”

The 21-year-old also added, “Wish u the best. Don't use my name for headlines. U are already on the cover. U don't need it. Just be honest. Big hugs bud.”

Clifford had his tail between his legs when he tweeted back, “@justinbieber done nothing but praise ur album; no idea why that's even in the article. big fan since the star man, take care.”

Despite what JB said, 5 Seconds of Summer did go to Bieber’s after party, which was at The Nice Guy in LA and the band was even photographed entering the bash!
