You can go ahead and start weeping for the future of humanity now: One of Lady Gaga's fake fingernails just sold for more than $13,000. The singer wore the black-and-gold acrylic nail, designed by Aya Fukada, at last September's launch of her Fame fragrance (see it in the gallery) and at the next day's concert in Dublin, Ireland, E! reports. In the auction listing, a stage crew member says he found the nail onstage after that performance. The winning bidder also received a photo of Gaga, onstage in Dublin, with the nail missing.
