 Cher stunned fans at the Billboard Music Awards by performing in a raunchy silver stage costume which left little to the imagination. #BBMAs: @Cher sings "Believe," marking her first award show performance in 15 years pic.twitter.com/MlvRt3U3er — Hollywood Reporter (@THR) May 22, 2017 
 
 People on Twitter are seriously wondering if this 1960s icon was lip syncing during this evening's performance of “Believe.” 
 
 Why the hell is Cher lip syncing? Cher, who turned 71 Saturday and received a slew of birthday messages (including one from Kim Kardashian on her social media channels, where she shared her top nine Cher style moments), made her return to the awards show stage after a 15 year hiatus performing her ’90s anthem “Believe” and her 1989 smash hit “If I Could Turn Back Time” of her nineteenth album, Heart of Stone. “I’m shocked that I can still run across the stage at my age. Speaking on today’s “Good Morning Britain,” he said: “At what point do Cher’s outfits become inappropriate? She’s 70.” 
 
 Co-host Susanna Reid said: “Oh yes because you have a cutoff, don’t you?
– Cher is 71, but that didn't stop her from rocking nipple pasties and a thong at Sunday night's Billboard Music Awards. The pop diva first performed "Believe" wearing pasties under a "dress" that was basically made up entirely of glittery fringe. She then took to the stage a second time to sing "If I Could Turn Back Time" while wearing the same black thong bodysuit she wore in the original music video, People reports. The performances marked her first time performing at an awards show in 15 years, Page Six reports. She also received an Icon Award at the Las Vegas event. See pictures of both outfits in our gallery. (But did she lip sync the performance?)
