Osbourne shows off plumped up taut face as she arrives for The X Factor bootcamp

Last year she vowed to never go under the knife again, insisting she wanted 'no more abuse' against her body.
But Sharon Osbourne, who has often spoken openly about going under the knife, looked surprisingly taut as she arrived at The X Factor bootcamp in London on Friday.
The rock matriarch showed off her plumper face as she joined fellow judges Nicole Scherzinger, Louis Walsh and Gary Barlow at the next stage of the televised singing competition.

'Fresh faced': Sharon Osbourne shows up to X Factor bootcamp in London showing off a plumped up taut face on Friday

And she will no doubt be raising speculation about whether she's gone against her vow and gone under the knife once more with her latest look.
Sharon, 60, went for an understated outfit in a white top under a black shirt, while she stood out slightly more with her red hair and green jewellery.
But it was her face which drew most attention as she chatted and giggled with her colleagues.
Osbourne, who underwent a double mastectomy last year, revealed on US show The Talk: 'No more, because I have been looking at pictures of myself recently since I started to lose weight.
'And in a lot of shots, my face looks plastic and at certain angles I was like, 'Oh, dear. Oh, I should never have done that. Oh, that's a bad one.' So I'm like, 'No more. No more abuse.''

Although it's not just for aesthetic reasons as Osbourne also decided to undergo the double mastectomy partially as a result of one of her breast implants bursting.
The 60-year-old added: 'One of them had burst, and all of it had gone into the wall of my stomach. And one breast was different than the other.
'I wasn't diagnosed with cancer, but I had the gene and one of my breasts was in a really bad state because of the implant.'
Osbourne has even gone as far as to advise her fans to not follow suit by undergoing cosmetic surgery to alter their looks.

Smiler: Sharon has previously insisted she'll stop undergoing surgery but has sparked speculation she may have undergone the knife once more thanks to her new look

She warned: 'Never have [implants] by the way.'
And she's previously said of her surgery: 'I got to the point where I realised I was abusing, I wasn't respecting my body. I was chopping it, changing it, and it's like, hey, you've only got like one body and you have to respect your body.'
She's now back concentrating on work now that she's returned to The X Factor after a couple of years break from the British show.

But while she stood out in some respects, it was Nicole who stole the show.

Scherzinger made sure she turned heads as she arrived to begin filming the bootcamp section of the popular ITV show on Thursday.

Dressed in a wide leg black trouser suit, the wife of Ozzy, looked ready for business and raring to go. 
Sharon, who showed off her perfectly coiffed deep red hair, was no doubt excited about her return to the show, replacing Tulisa this year.

Nicole also looked ecstatic to be there as she showed off her impressive figure in an interesting ensemble consisting of a red double zip skirt and a white top with a cut-out detail and racer straps.
It was however her hair which raised the most eyebrows as the singer, who is the face of Herbal Essences, wore her locks in an interesting bun with the front section falling loose to frame her face.
Revealing her slim legs the skirt fell just below her derriere and her lithe legs looked even longer than usual with the help of a pair of black stilettos. 

Her co-judge Louis opted for a different look to usual –wearing a black open neck shirt with his suit.
The Irishman was no doubt feeling slightly emotional as he recently confirmed this would be his last year on the show – so his final time attending bootcamp.
Standing a little bit aside from the rest of the group was head judge Gary Barlow, who looked surprisingly casual for the day’s activity.

Hair raising: Nicole showed off a very interesting hair style which complimented her fashionable dress

Wearing a pair of dark green chinos with a short sleeve blue shirt, he added a pair of blue shoes which didn’t particularly match the outfit. 
Taking to Twitter during the morning, Gary wrote: ‘Beautiful morning ! Boot camp starts today #XFactor’
The gang appeared to all be getting along very well and were seen laughing and joking with each other before heading in for a hard day of decision making.
It’s not just the change of panel which makes the 10th series of the X Factor different, hopefuls will - for the first time ever - have to tackle two sets of auditions.  First, they will face the judges eyeball to eyeball in an intimate audition room.
If they receive three or more yeses here they will then have to perform for the judges once more, this time in an arena, to prove they can also impress an audience before securing a coveted place in the next stage in the competition – bootcamp
