Lady Gaga talks age: 'I feel like I have lived 100 years'

Lady Gaga says she feels "old" despite being aged only 29.

The singer told News.com.au that she feels like she has lived for many more decades as a result of her fast-paced lifestyle.

The US star said: "I have been in the business since I was 15, and although I have been famous for only seven years and lived 29, I feel like I have lived 100 years.

"And I feel f***ing old."

Gaga meanwhile said in the same interview that she felt like an outcast at school due to an inclination towards being "lonely".

She said: "I did feel very isolated as a young person, and not because I was alone or abandoned by my family, it's just a chemical thing. Some kids are born like that. We don't know why we feel lonely, but we do.

"It's like depression but it's not because someone neglected me. I grew up in a very disciplined household. I played piano when I was four. I sat at it and I started to play it. Did my parents then say to me that we are giving you lessons? Yes.

"And then when I tried to stop playing they said, 'You can sit there for an hour and practise, or you can sit there for two and not practise."

Lady Gaga meanwhile is currently writing the follow-up to her 2013 album 'ARTPOP'.
