Justin Timberlake has opened up to Rolling Stone about fame, revealing the showbiz spotlight has cost him a number of close friends since he burst onto the scene as a member of Disney's The Mickey Mouse club.
The former NSYNC star - who is back with his forthcoming album The 20/20 Experience - told the magazine: "The older you get, the more you realise people come in and out of your life and you realise that person changed or that person wasn't exactly who I thought they were.
“And I found with friends, close friends that have come and gone in my life, they're like, 'Oh, you changed. Everything else around you changed, you're still the same person.'
"If you want to say that I didn't have to worry about a paparazzi following me around in my car has made me change, then yeah, I'm sorry, I've changed but I didn't know what that was like before.”
He added: “I was just a young person trying to express myself. It's just a crazy world that we live in. I don't want to paint a picture that's jaded or anything because I'm super happy to be back and doing it and I have a great time where ever I go. But the things around you change the older you get and that's just life.”
JT also went on reveal that his six-year break from music had nothing to do with his movie career, stating: "I would have taken a break regardless of if I would've done films or not because my last record was all-consuming and to go on tour like that, for me, I will not be the type of artist that puts out 10 to 15 albums.
“That's just not who I am. They're really special to me. I write music all the time, but until you really feel that desperate need to shout from the rooftops and express yourself in that way, I just kind of keep it to myself.
“I enjoy making music so much that if it doesn't come out, that's okay.”
Justin - who married actress Jessica Biel last year - is due to perform new song Mirrors at The Brit Awards 2013 next week.
