Megan Fox's stunning appearance may not be entirely her own, with cosmetic surgery 'experts' claiming the actress appears to have had breast enhancement surgery, a nose job and lip-plumping injections.

According to a new report, Megan has transformed herself from a pretty brunette into a raven-haired vixen who more closely resembles Angelina Jolie than her former self.

The 'experts' tell In Touch, “Her upper and lower lips appear fuller. It looks like she had Restylane or Juvéderm injections.”

“The bridge of her nose is thinner and the tip is more refined. The well-defined contour of an implant is apparent. She was probably an A cup and became a large B.”

Megan has admitted to suffering from low esteem in the past, which may explain her confidence-boosting surgery.

The Transformers beauty confessed, “I don’t feel very attractive or feminine, I feel like a boy.”
