Lady Gaga's fake fingernail has been auctioned for $12,000.

An enthusiastic fan of the "Edge of Glory" hitmaker has laid claim to one of the intricately-designed false nails worn by the singer at the launch of her Fame perfume and during her Born This Way ball tour last year after paying a five figure sum for the unique item.

Gaga, 27, adorned herself in black acrylic nails featuring detailed gold embellishments - which were designed exclusively for her by New York nail artist Aya Fukuda - last September, but the singer appeared to lose one of the nails while gyrating on stage in Dublin, Ireland and it was later picked up by an eagle-eyed stage hand after the concert, who promptly sold online.

In the official auction listing, the crew member explained, "I noticed an object on the floor of the stage, which at first I thought was a guitar plectrum. When I picked it up, I saw it was an acrylic nail."

It's not the first time one of Gaga's eager fans - who she affectionately calls her Little Monsters - has paid good money for a piece of the star. In 2010, a Russian billionaire reportedly paid a cool $1 million to feature alongside the Grammy Award winner in her nine-minute Alejandro music video.
