Vanessa Bryant has denied that she has been under the surgeon’s knife after reports suggested she had sought cosmetic help to stop philandering husband Kobe from straying.

Vanessa Bryant’s representatives have blasted the allegations as “100 per cent not true” and “ridiculous”.

During her appearance at the London Olympic Games, Vanessa Bryant, 30, set tongues wagging that she had undergone surgery after pictures of her looking rather different from her former self emerged.

A source told The National Enquirer that Vanessa Bryant was starting to feel “insecure” about her looks and “would do anything to keep Kobe happy”.

Not only had she made obvious changes to her hair, which once bared blonde highlights and is now raven black, but her skin tone, pout, brow and tip of the nose appeared to belong to someone else.

Plastic surgeon Dr. Anthony Youn offered his expertise to the US publication, saying: “Vanessa appears to have undergone some plastic surgery.

“Her nose is thin with what appears to be scars at the base of each nostril. In some people, this is a telltale sign of a nose job.”

The medical professional – who practices in Troy, Michigan – also stated that Vanessa Bryant’s lips look to have been plumped, “possibly from an injectable filler like Juvederm”.

Following Kobe Bryant’s rumored reputation of playing away from home, including an admission to one particular infidelity in 2003 and pictures of him shirtless with two women during a recent nightclub venture, Vanessa is said to be “obsessed” with her looks in a bid to stay young and youthful for her husband of 11 years.

A source told the Enquirer: “The sad thing is that Vanessa is wrecking her natural beauty.

“She started freaking out over a few crow’s feet, and the next thing you know she was getting a full facial makeover… she is extremely insecure.

“She’d do anything to keep Kobe happy.”

The on/off couple has had a somewhat turbulent romance over the years and was on the verge of divorce just two months ago.

But during the London Olympics, they appeared to have reconciled and were seen laughing in the stands during a swimming final with their six-year-old daughter Gianna.

However, Australian Olympic gold medalist Stephanie Rice was still forced to deny she was having a fling with Kobe Bryant after they were seen during a cycling event together.
