The Beady Eye frontman says he is big fan of 19-year-old popstar, whose supporters are known as Beliebers, reported Contactmusic.
Defending the singer after he went on stage two hours late at London's The O2 last month, Gallagher said, "Anyone who goes on two hours late is right in my book, man. All these so-called rock bands that sit backstage going, 'Hey, let's wait 15 minutes'. Wait two hours and 15 minutes! No one will beat that, ever. So get off his back, I am a Belieber."
"My theory is that it's gonna have BE on the cover, and then on the back IEBER. Bieber! I've got his back," he added.
