62-year-old Cher performed at the David Foster and Friends concert in Las Vegas this weekend wearing a recreation of her iconic 1992 look for "If You Could Turn Back Time." Thanks to the modern marvels of plastic surgery, she looks virtually no different than she did when she first wore the outfit 17 years ago. In fact, if they hadn't put her belly-button back on in the wrong place, I don't think I would even been able to tell the difference at all.
