London, June 20 (IANS) 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’.
