Tulisa
Before Tulisa was still blowing audiences away on X Factor, she had already decided that she needed to fix her teeth. She reportedly spent over $15,000 on a set of new chompers, despite not having received a record deal, let alone a signing bonus. However, the investment ultimately paid off.
She spent quite a lot on fixing her gumlines to make her teeth appear longer and less childish. Tulisa opted out of getting veneers since her dental budget was already exploded as it was. Thankfully, she became somewhat of an international success after X Factor, and the money she used to fix her teeth was more than covered.
