Sharon Osbourne, 71, surprised fans with her dramatic appearance at Taylor Swift's Eras Tour concert in London, where she wore a sweatshirt advocating for Swift's presidential candidacy. Her re-creation of a memorable 'X Factor' audition moment caused a stir, with many fans remarking they hardly recognized her and speculating about her use of the weight-loss drug Ozempic, which she has previously discussed. Sharon admitted to losing too much weight from Ozempic and expressed a desire to gain some back, stating she currently weighs under 100lbs. Fans took to social media to express their shock over her gaunt appearance, raising concerns about the drug's effects. While Osbourne has made critical comments about Donald Trump in the past, Swift has yet to endorse any presidential candidates ahead of the upcoming election.
