And now the transformation is complete.
Following her X Factor style makeover, new judge Tulisa has reportedly forked out £12,000 to finish the look with a gleaming Hollywood smile.
A source told The Sun: "Tulisa has not got bad teeth by any stretch of the imagination. She's hardly Austin Powers.
"She had a few problems when she was younger but nothing serious. Since she became famous she has become aware they are not perfectly aligned, so she decided to pay for a bit of help."
Apparently that "bit of help" included a suitably expensive set of pearly white veneers which will make their debut during the judges' houses phase of the competition.
We can't blame Tulisa for wanting to look her best for her first big TV job but we've got a sneaking suspicion Simon Cowell may have been working his magic again.
After all, even Louis Walsh succumbed to surgery in the end.
