Tulisa was one third of 'streetwise pop crew' N-Dubz.
In 2011, Tulisa was announced as one of the new X Factor judges (and was unofficially considered Cheryl's replacement).
In the first episode of her 'judging career' she was verbally 'attacked' by a young man and was able to take a classy moral high ground, the show's producers thus managing to quell any fears that she would be too mouthy and aggressive.
Hurrah.
In 2012 an ex 'beau' decided to put a video of his erect wanger onto the internet. Unfortunately Tulisa was in the background but nobody really noticed.
Tulisa expertly 'changed the conversation' by putting another video onto the internet. She did quite a lot of seriousface in that video.
A few days later she appeared with ANOTHER video, this time for debut single 'Young'. It was a song about not being judged if you're young or something. She video featured various 'japes' taking place in a foreign location. The song was very good. And thus Tulisa's solo career was officially... OPEN!
Unfortunately she then released a song 'for the R&B heads' that no one really liked, looked bored throughout The X Factor, seemed to hate being a popstar and watched her album, 'The Female Boss', enter at Number 35.
