The 36-year-old star recalled his early career when he went for dinner with One Direction's Niall Horan, and said he can relate to the blonde hunk, as he also found success at a young age as part of a boy band, reported Contactmusic.
"One Direction came on 'X Factor' and Niall and I hung out a little bit and went out for dinner. He's a great lad. They're living the dream, but they're working so hard.
"I know what it's like when you don't get to appreciate what you're doing. I wish we had enjoyed those first six years of Boyzone more, but 1D look like they're having a good time.
