Tulisa Contostavlos wanted to ''dig up dinosaur bones'' when she was younger.
The 24-year-old star was planning a career as an archaeologist while she was at school but when she discovered how long it would take before she was qualified the blonde beauty set about trying to become a singer instead.
She said: ''When I was seven, I wanted to dig up dinosaur bones. I just thought it will be so long until I can be an archaeologist, so I picked up a mic.''
The 'X Factor' judge - who shot to fame with pop band N-Dubz alongside her cousin Dappy Contostavlos and ex-boyfriend Fazer - admits she is a ''controversial'' character and is looking forward to revealing the ''truth'' about her early career in forthcoming autobiography 'Honest'.
Speaking to UK TV show 'Daybreak', Tulisa - whose ex-boyfriend Justin Edwards leaked a sex tape of the pair online earlier this year - added: ''I'm one of those controversial celebs or whatever you want to call it, but I'm actually a musician, people forget this.
''I'm happy for people to judge me - I've taken that on board by doing this job, so I'm ok with that - but if you're going to judge me, judge me on the truth, and the truth is in the book.''
