Why not? I've met Justin, and he looks like a guy in his twenties, so I've no reason to assume he'd lie about it. He's totally secure about his wonky teeth and receeding hairline, I don't imagine his age would bother him!
I wasn't referring to his "wonky teeth" or "receding hairline" just his overall appearance. I asked about his real age as I heard a conversation on 6 music the other day between a couple of djs who referred to some "relevation" about his real age. I was wondering if anyone else had heard anything? Personally I think he looks at least 35.
He's skinny and a smoker, that's why he looks older, his cheeks are kinda sunken, that and his teeth and hair make him look a lot older than he really is.
