Norah Jones says turning 30 helped her record a “more personal” album.

The “Don’t Know Why” singer believes reaching the milestone in March forced her to reassess her life and had a change in her creative approach to making The Fall, which has sold over half a million copies since being released last month.

“It seems to be an age where everyone goes through changes. All my good friends have. Everyone’s either breaking up or getting involved or married or having a baby,” she said. “So when I made that album I think I was looking outside myself more at that time, because of where I was and what was going on in the world. The past couple of years, though, I’ve looked inward more.”

Norah - who split from long-time boyfriend Lee Alexander earlier in the year - also says she feels no pressure to recreate the huge success she had in her 20s.

“I don’t feel like I have anything to prove now. My label actually was excited about me trying something new,” she told USA Today. “I have a lot of support and a lot of freedom. It’s a good place to be in.”
