Ke$ha was a ''serial breaker-and-enterer'' when she was younger.

The 'Tik Tok' star was desperate to get her early tracks heard, and would stop at nothing to get the biggest stars to listen to her songs, once breaking into Prince's house to try and give him a demo.

She said: ''I was a serial breaker-and-enterer when I was a kid. It wasn't just [Prince]. I have never had the chance to speak with him about it. I think we could do good work together because I see commonality in our interests.''

The singer has come a long way in the celebrity stakes since getting her first big break singing the chorus of Flo Rida's 'Right Round' in 2009, and has recently recruited punk legend Iggy Pop and the Flaming Lips' Wayne Coyne to appear on her second album 'Warrior', which she lists among her greatest achievements.

She told Q magazine: ''To get Iggy and Wayne in the studio is up there. But I think my greatest achievement was to see my mother crying with joy dressed as a penis in front of a crowd of 300,000 [in Hungary, 2011] was the fulfilment of my dreams.''
