Megan Fox caused quite a stir when she showed up to the 2009 premiere of Transformers: Revenge of the Fallen with a noticeably swollen face.

Since then, Fox has grown tired of the criticism she's been getting on her "cosmetically altered" face, so the sexy 25-year-old actress took to her Facebook and uploaded some photos with the album caption, “Things you can’t do with your face when you have Botox”.

In the pics, the sexy star furrows her brows and points out naturally occurring lines in her forehead when she raises her eyebrows -- things that cannot be done if you've got Botox ... right?

In an interview with Allure magazine last year, the Passion Play star adamantly denied she's had her lips filled in. Fox confessed:

    "My lips are my lips. 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."

After taking a look at her pics, do you think the Armani spokes model is 100% natural?
