Fangs a lot: New X Factor judge Tulisa Contostavlos revealed her new £12,000 smile at the launch of the X Factor in London today after having veneers to cover her old teeth, as seen in November 2009 (right)



has now quite literally put her money where her mouth is.



The new X Factor judge has apparently splashed out £12,000 on a gleaming new Hollywood smile - just like Cheryl Cole did before she made her debut on the show.



The 25-year-old brunette beauty debuted her new teeth on the red carpet today at the official launch of the new series of the show at London's O2 Arena.





Girlpower: Tulisa Contostavlos (L) and Kelly Rowland (R) appeared to be best of friends already as they arrived at the X Factor press launch at London's O2 Arena today





Wearing a tight patterned black stain Vivienne Westwood dress and black high heeled platform mary janes, she also premiered a glamorous new sideswept hairstyle with blonde highlights across the fringe.



Tulisa's father Plato Contostavlos confirmed that his daughter had treated herself to new gnashers - and joked he hoped she'd pay for him to get some too.



He improved too, telling The Sun: 'She’s had her teeth done for £12k, why not if it makes her feel better? I want to have mine done for £20k.'





Stylish: The N-Dubz star has ditched the tracksuits and bling for a far more classy appearance, and looked lovely in her Vivienne Westwood frock





Plato added that he understood the pressure Tulisa was under to look good in front of the cameras.



He said: 'She’s beautiful in my eyes because she’s my daughter, but it’s every girl’s dream to improve and to want to look even more beautiful.



'It’s the industry she is in, she needs to look her best. She doesn’t tell me she feels pressurised to look good since she joined The X Factor but she’s a girl, she’s young, of course she does.





Glamorous: The 25-year-old looked comfortable in her own skin as well as a red carpet natural as she met fans outside the venue





'That’s the showbiz life she’s chosen and she wants to stay in it and do well.'



It was recently reported that ITV bosses have splashed out £70,000 on a makeover for the N-Dubz star, in a bid to get her to ditch the shell suits and bling and become more classy.



A production source said at the time: 'They put aside so much for Tulisa because you don’t get a second chance to make a first impression.'





X Factor makeover: Cheryl Cole also underwent a style change - including new teeth - before she appeared as a judge on the show





Of her new dental makeover, a source had previously 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.'



Tulisa's predecessor Cheryl also had a smile makeover ahead of her judging role on the X Factor.



The X Factor returns to our screens this Saturday on ITV1 at 8pm.
