The mystery girl holding the mobile phone in Megan Fox’s new commercial has been identified.

Viewers were said to have realised that the hand in the Super Bowl ad could not belong to the actress, famous for her stumpy thumbs.

The hand double was later revealed to be Pamela Moses, who was apparently asked to send pictures of her hands, The Sun reported.

Little did she know her fingers and traditionally-shaped thumb would catch the eye of billions of TV viewers.
