The 'Toxic' singer has learned to relax and focus on her own interests since her much-publicised breakdown in 2007.

She said: 'I'm learning to take better care of myself and not get stressed or down about things for nothing. I'm taking my time these days and not letting myself get under any pressure other than to just feel happy about myself and to work on my music.

'I want to show people I am a strong woman. I have a lot of great things ahead of me that I want to accomplish.

'I feel positive and much happier, things are looking good again. I'm learning to relax and not place so much pressure on myself.'

The 'Womanizer' star says working on her recent album 'Circus' was key to helping her move forward with her life.

She added: 'I've been through a lot and I'm really excited by my album. I'm very proud of it. I really enjoyed the process of putting the album together and it's been kind of therapeutic for me. Music is such a huge part of me.'
