Looks like X Factor style overhaul is complete, as she showed off a gleaming new smile on the red carpet yesterday.
The new judge couldn't contain a grin at the official launch event for the new series, and now we know why. She's had a mouth makeover...
Tulisa's father Plato Contostavlos, confirmed the cosmetic dentistry to The Sun.
"She's had her teeth done for 12k, why not if it makes her feel better?" he said.
"She's beautiful in my eyes because she's my daughter, but it's every girls' dream to want to improve and and to want to look even more beautiful."
"It's the industry she's in, she needs to look her best," he added.
