5 Seconds of Summer star Michael Clifford was upset after James Corden poked fun at him while filming a sketch recently.
The guitarist and his bandmates - Luke Hemmings, Calum Hood and Ashton Irwin - filmed a skit for James' 'Late Show' where he pretended to be their fifth member but James reportedly got annoyed when they kept stepping on his lines and took it out on Michael.
According to Rolling Stone magazine: "His jokes at the band's expense seemed to get harsher, and he singled out Clifford: 'I can find a d***head with red hair seven days a week! You think you're the first guy to dye your hair and be in a band? You're like a cliché of every s**t musician."
A "shaken" Michael said after filming: "That was really weird. That was the hardest promo I've ever done."
The meanest insults were left out of the sketch when it aired.
Meanwhile, Ashton revealed that Michael is a homebird and prefers to be at home rather than on the road touring.
He said: "Michael loves home. He loves being at home with his computer. That's where we picked him up from and that's where we have to drop him back. You know what I mean? Michael, if you'll just leave your computer for a couple of years, and we'll drop you back there eventually. We just need you now for this band."
