Hollywood actress Megan Fox has sparked rumours of going under the knife after she turned up at a movie premiere with utterly smooth, mask-like features.

"Megan looked gorgeous - everyone's jaws hit the floor. But her boobs didn't look natural," thesun.co.uk quoted a source as saying. The actress was in Los Angeles for Thursday's premiere of Jonah Hex.

A Hollywood source said: "Megan was so naturally sexy - that's why she was considered the best-looking woman on Earth. But recently she's looked too skinny, stiff and a little fake".
