(Cover) - EN Star Style - Megan Fox has silenced Botox allegations with a series of carefully posed photos.

The Hollywood actress set out to defend allegations that she had enhanced her facial features with the cosmetic procedure.

The 25-year-old star, who is famed for her stunning beauty, posted four pictures on her Facebook page on Thursday under the headline Things You Can't do with Your Face When You Have Botox.

The gorgeous brunette is seen making a number of facial expressions in a bid to silence the speculation.

Megan is frowning in one picture, and pointing out the lines in her forehead, while another photo sees her pulling a surprised expression with her brows raised.

Megan has previously addressed the subject of cosmetic enhancement. The American star says there is a deeper problem that needs to be considered before undergoing life-changing surgery.

"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. If, then, you feel, this is something that I want to do, then do it," she told Allure magazine. (C) Cover Media
