After weeks of hilarious hopefuls, seat swapping and some jaw-dropping double auditions, X Factor's class of 2013 finalists has been chosen as we gear-up for the live shows kicking off this weekend. But here at Transform, we're more interested in those on the other side of the judging desk.

We're pleased to say that Sharon, Gary, Louis and Nicole have got it spot on when it comes to making the most of their looks. We're often approached by the media for our expertise on the treatments celebrities may (or may not!) have had and this week our Non-surgical Director Anne Marie Gillet spoke with Bella about the judging panel.

Happy birthday to queen of rock Mrs O, 61 today and still looking ah-may-zing! Sharon is no stranger to surgery, having been what she calls 'tweaked, stretched, peeled, lasered, veneered, enhanced or removed altogether' for a reportedly estimated £120,000. Anne Marie comments 'Sharon has recently stated she's choosing not to have any more surgery and this is probably for the best. She's got her look just right. All she needs to do now is maintain with light treatments such as facial peels to keep her skin looking good.'  

Louis has never been shy when it comes to cosmetic treatments, having undergone blepharoplasty (eyebag removal) and a hair transplant, as well as rumoured for having line and wrinkle smoothing treatments. Anne Marie says Louis may have had line and wrinkle treatments such as Botox® on his forehead and around his eyes.

Whilst Gary, 42 has yet to go under the knife, the Take That star has struggled with his weight for years. 'Gary is a great example of someone who has worked hard in the gym and kept an eye on his diet', says Anne Marie. 'These are important factors for youthful looking skin and a good physique. Non-surgical treatments can enhance what is already there but they can't be used as a substitute to a healthy lifestyle!'

At just 35, Nicole is the youngest member of the panel. Like Gary she is yet to indulge in surgery and non-surgical treatments. She certainly works hard to maintain her figure and has no issues flaunting it - she's certainly got it, so why not flaunt it?
