Natalie Imbruglia considers herself to be ''a survivor''.

The Australian pop star thinks she's become tougher following her divorce from rocker Daniel Johns, 36, over seven years ago - but has admitted she's still prone to feelings of isolation.

Speaking to Australia's OK! magazine, she said: ''Standing on my own two feet for so long has made me self-sufficient. I'm a survivor. And sure, I can get lonely sometimes, but then you can get lonely in a crowd.''

Natalie, 40, is currently single and has had a number of relationship since her split from Daniel, whom she married in 2003 and divorced in 2008.

However, the 'Torn' hitmaker admitted she prefers to keep her romances close to her chest.

She said: ''I have been in love and had relationships, you just don't hear about it because I'm a private person.''

Meanwhile, Natalie confessed recently that her high level of fame almost sent her ''insane'' due to her Obsessive Compulsive Disorder.

She said previously: ''I was anxious, nervous, stressed out and scared. I didn't want to go outside in case people recognised me. It nearly sent me insane. I felt I had to live up to 'Torn'. I didn't write it, but I was a part of the reason it was so successful.

''I felt so much pressure to live up to those expectations, then I was expected to top it. That was really hard for me.''
