Adam Lambert on growing up: 'I refuse to be spoken to in a certain way'

'Ghost Town' superstar Adam Lambert has revealed that he's grown a lot over the past few years and has learned a lot about self-respect and attitude.

During an interview with Details magazine, the hitmaker explained that he now feels as though he has grown into an adult and has made some big steps in his life over the last couple of years:

"For the first time in my life, over the last year or two, I feel like I'm a f**king grown-up! I definitely have a little dash of Peter Pan syndrome somewhere, where I always have a childlike attitude towards things. But I bought my first house this year, I have a business, I've done a lot for myself, and I've done a lot for my career."

"And all of a sudden, I'm realising: 'You know what? I'm a grown-ass man! I will not be talked to a certain way. I will not be treated a certain way.' Having self-respect is part of that, too. And I've had my ups and downs with that my whole life."
