Megan Fox posts facial expressions on Facebook to prove she's not had Botox

London, July 9 : Megan Fox has taken the help of her Facebook page to squash reports of her possibly using Botox to liven up her skin.

 The actress silenced the rumours by posting a series of pictures on her Facebook page in an album entitled 'Things You Can't Do with Your Face when You Have Botox', reports the Daily Mail.

Fox tried to prove that her forehead muscles are not frozen as she clicked herself indulging in a number of facial expressions.

In one shot the former 'Transformers' star created frown lines, while in another she was seen wearing a worried expression, and points to the lines on her forehead.

The 25-year-old also attempted to depict a shocked face in another snap.

In the final shot, Fox suggestively stared at the camera, displaying a perfectly-arched eyebrow.

Fox's recent red carpet appearances, where she looked flawless with plumper lips, sparked rumours that she had resorted toplastic surgery or injections.
