Sharon Osbourne and Louis Walsh's Evolving Looks: Viewers of Celebrity Big Brother Dub Them 'Unrecognisable' - OK! Magazine

On March 4, Monday, followers of Celebrity Big Brother were delighted to see the popular TV show return on ITV, featuring some very familiar celebrity faces. However, two of these faces noticeably stood out due to their drastically changed appearances.

Close friends and ex-X Factor judges, Sharon Osbourne and Louis Walsh, were the first to set foot inside the renowned house during the launch packed with celebrities. Surprisingly, some fans claimed that the septuagenarians, who have been absent from their judging roles for nearly a decade, appeared to have been substituted by their doubles.

An intrigued viewer turned to X - the platform formerly known as Twitter - to comment on Sharon's transformed look and the amusing prospect of her being an “unrecognisable” substitute.

The viewer remarked: 'Sharon appeared terrible with her weight loss. She resembled a porcelain doll. Maybe it's not even her.'

Sharon has always been candid with her fans regarding the plastic surgeries she underwent over the years. More recently, she voiced out her regret over the weight loss she achieved using the contentious diet drug named Ozempic.

A separate viewer stated: 'Oh my goodness, Louis and Sharon look terrible.' Another speculated if 'Louis can still recognize Sharon with her new face' after Louis, the Irish TV celebrity, entered the house as the second contestant and found Sharon sitting all by herself on the sofa.

A diehard Sharon fan defended the celebrity saying, 'I'm obsessed with Sharon Osbourne and her new face.'

Sharon, with her fiery red hair, looked glamorous in a black blazer adorned with a white carnation. She looked evidently surprised upon learning she would be assessing her new housemates. Louis showed up looking smart in a traditional suit and shirt.

The introduction of Sharon and Louis into the house was a huge hit among viewers. Fans were engrossed by their secret task, which they termed as 'quite brutal.' The daring duo was instructed to judge which housemate deserves eviction first, thereby deciding the trio that will face the public vote.

This early live twist in the show will keep fans engaged as they see Gary Goldsmith, the uncle of Kate Middleton; David Potts of Ibiza Weekender fame; and social media celebrity Zeze Millz, 35, face the threat of eviction.

Sharon first gained fame on X Factor as a judge for the first four series from 2004 to 2007. It's no surprise that she's experienced changes over these many years. She returned to the show for the 10th series in 2013 before wrapping up with the 13th and 14th series in 2016 and 2017. Louis has been her companion during all her stints as a judge.
