Tulisa was deeply unprofessional in many ways.
1. She ruined any chance Misha B had of a career by branding her a bully when according to Janet Devlin and Craig Colton it was one argument that Misha B had with one of the Little Mix girls.
2. She didn't know her Rock Music which on a UK Singing Show is shameful considering it's one of the top 3 genres in the UK, and my personal favourite Music genre.
3. Her "mentoring" of Ella Henderson and Jade Ellis in series 9 was nothing short of a criminal offense in Music terms.
4. I can't remember one constructive or interesting comment that she ever made on the show.
