With the blankest of blank expressions on their faces, these mysterious figures have been popping up in the most unlikely of places. The faceless mutants have a penchant for A-list celebrity bashes and have been spotted at Elton John's White tie ball and Harrods summer sale, opened by Sex and the City star Kim Cattrall.
With a membrane of skin stretched tightly over their eyes, noses and mouths, the alien-like figures were most recently snapped 'watching' a match perched on Murray Mount at Wimbledon.
Close inspection of the pictures rules out an alien invasion - small perforations around the eye areas of the masks allow the people beneath to see the world outside. But nobody knows who the faceless figures, who often appear as motionless couples are, or why they are turning up at high profile events.
Theories include the possibilities that they are limelight-seeking pranksters, performance artists or that they are at the centre of a viral marketing campaign for an as-yet unknown product of forthcoming horror film. Speculation has even arisen that the masks hide a pair of well-know faces, fed up with being harrassed by the paparazzi. This faceless figure even has his own driver, fuelling speculation that the man behind the mask may be a celebrity himself. One blogger wrote on the Moue Magazine website: "They probably aren’t just random people off of the street. "If it ends up being a pair of celebrities who have had it with being photographed all of the time and are staging a protest, I vow to support every project they appear on from now on."
