Untransformed: Megan Fox proves she hasn't had Botox

Megan Fox has rubbished reports that she has had Botox treatment and to prove her point she has posted an album entitled "Things You Can't Do with Your Face when You Have Botox", which contains a series of her pictures, on her Facebook page.

In one of the photographs, she is seen frowning — demonstrating that her forehead is capable of wrinkling. Another photo shows her putting on a shocked expression, reports contactmusic.com.

The actress, who has been under constant scrutiny for allegedly having had treatment, has previously said: "My lips are my lips."

She also encouraged women to speak to a therapist before undergoing cosmetic 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."
