Megan Fox has been dogged by allegations that she has undergone plastic surgery for years, something she has consistently rejected.

On Thursday, the brunette beauty shared a photo album titled “Things You Can’t Do with Your Face When You Have Botox” on her official Facebook page.

One photo shows her frowning to illustrate her ability to wrinkle her brow, while another shows her creating a shocked look.

Megan gazes suggestively at the camera in the last image, arching a flawlessly groomed brow.

While over 64,000 individuals have “so far “liked” the album, the comments reflect a wide range of viewpoints, from die-hard Fox fans to disbeliever.

The 25-year-old denied ever having fillers injected into her renowned pout in an interview with Allure magazine last year.

“My lips are my lips,” she told the magazine. “I would encourage anyone to first speak with a therapist, to try and figure out where this want comes from, because a lot of times it’s not related to your teeth or your nose or your chin — the surgery is not going to alleviate that insecurity for you.”

She added: ‘If, then, you feel, “This is something that I want to do,” then do it. It’s amazing that we have the technology to do the stuff that we do.’

Megan’s latest commercials for Giorgio Armani’s summer 2011 cosmetics collection were unveiled this week, and they show her maintaining her natural beauty.

Fox, 25, isn’t the first star to utilize social media to debunk cosmetic enhancement allegations. Teri Hatcher, star of Desperate Housewives, shared identical photos in August 2010 to establish that she is devoid of fillers.

Megan looks great in the advertisements, which feature her in a variety of make-up styles ranging from dewy, natural beauty to dramatic red lips and smokey eyes.
