Cher’s return as the musical guest on “Saturday Night Live” stirred up more chatter online than the sketches themselves. She performed “DJ Play a Christmas Song” and “Run Run Rudolph” on the show’s final episode of the year — but many viewers were convinced she wasn’t singing live. Social media lit up with accusations of lip-syncing, with fans pointing out that her microphone was often nowhere near her mouth. Some called it obvious, some called it sloppy, and others said the lack of effort to hide it somehow made the performance even more “camp.” A wave of viewers compared the moment to Ashlee Simpson’s infamous 2004 SNL lip-syncing meltdown, when the wrong backing track played and she famously danced offstage in panic. Several fans joked that Cher had just delivered the most noticeable lip-sync since that incident.
