Lady GaGa has created a dress out of images of her fans' faces.

Dubbed 'The Masterpiece', the pop superstar - who famously wore a gown made entirely out of meat to the MTV Video Music Awards in 2010 - fashioned the skimpy leotard and flowing train after thousands of her 'Little Monsters' sent in pictures of themselves as part of the star's new MAC Viva Glam campaign.

Created by Gaga's resident stylist Nicola Formichetti, the images have been printed on to fabric the same colour as the 25-year-old singer's new lipstick for the cosmetics brand, which will raise money for AIDS awareness causes.

Despite her eccentric fashion choices, the 25-year-old singer - real name Stefani Germanotta - managed to go unrecognised when she went out make-up free to a London pub last week.

An onlooker at the Duke of Wellington pub in Chelsea told the Daily Mirror newspaper: "Staff didn't recognise her. She had no make-up on and very normal clothes, just baggy trousers and butch, black, flat shoes. And definitely no wig.

"Gaga was chatting to staff, complimenting one on her Tattoo. But within half an hour she was overheard saying, 'This is crazy, I can't believe no one recognises me.' Weirdly, she then started making outrageous comments to people passing by and generally drawing attention to herself."

Meanwhile, the singer has won a court injunction against a cartoon character called Lady Goo Goo after lawyers ruled there was a link between Gaga and the nappy-wearing baby that appears on website Moshi Monsters.

Lady Goo Goo's tune 'Peppy-razzi' - spoofing Gaga's 'Paparazzi' - caused her to become an internet sensation, but London's High Court has now banned Mind Candy, the British parent firm of Moshi Monsters, from distributing any more tracks by the cartoon character.

Michael Acton Smith, founder and CEO of Mind Candy and creator of Moshi Monsters, said: "This court ruling is a huge disappointment. It's pretty obvious that kids will be able to tell the difference between the two characters.

"It was all done in the name of fun and we would have thought that Lady Gaga could have seen the humour behind this parody."
