Kelly Osbourne's Unrecognizable Look In New Video Has Fans Worried: 'That's Not Her, Is It?

Kelly Osbourne has left fans shocked as she took to social media to debut a new blonde hairdo, which made her look unrecognizable.

It comes after she and her mom, Sharon Osbourne, paid tribute to the late legend Ozzy Osbourne on what would have been his 77th birthday.

Kelly Osbourne has been open about her 85-pound postpartum weight loss and has denied using the miracle drug Ozempic to achieve it.

Kelly Osbourne hard-launched her stunning new look with an Instagram post on Monday, leaving fans lost for words.

The TV personality and daughter of late rocker Ozzy Osbourne can be seen sporting a full blonde look as she reads a children's book, "The Dog With No Fur," which talks about kindness and self-acceptance.

She also showed off her slimmed-down look in a V-neck long-sleeve black top and black high-waisted trousers. Before the new video, Kelly stuck with different shades of purple hair and, at one point, changed it to a silver color.

Kelly seems to be ringing in the Christmas season in style as she also shared a photo of herself, her mom Sharon, and her son, Sidney, posing alongside Santa Claus in what appears to be a Christmas party. A video included in the post showed the young star attempting to open a gift box with Santa Claus, who then opened it to reveal a musical instrument.

Fans took to the comment section of her post to share their reaction to her new look, with many of them pointing out how she looked unrecognizable.

A fan wrote, "Her transformation is visually crazy, if we compare her reality show era to now."

"The only way I recognised her was that she sounded like her mother," a second fan penned, while another asked," 'That's not her, is it?"

A fourth person commented, "If I didn't see her name, I never would've known that was Kelly Osbourne. What the actual F?"

Some fans expressed worry, with a person writing, "Oh, Kelly. Please, whatever you are doing, stop. Please stop."

Another attributed her transformation to a weight loss drug, commenting, "Put the ozempic down."

This Christmas would be the first the Osbourne family would celebrate without their patriarch Ozzy after he passed in July at the age of 76 after a long battle with Parkinson's disease.

For what would have been his 77th birthday on December 3rd, Kelly and Sharon paid tributes to him in their own way. Sharon shared a compilation of tributes and eulogies from fans and photos of them together.

"My darling husband, I celebrate the day you were born. I will never let go of your hand until I see you on the other side," she captioned the post, per People Magazine.

Kelly also shared an Instagram reel of her father laughing. Over the video, she wrote, "miss Ozzy's smile," and captioned the post, "I promise to never stop smiling!"

Kelly broke down in tears on her first TV interview since the Prince of Darkness's passing, as she admitted to struggling with the grief from his death.

The pre-recorded interview, which was shown on the BBC, featured Kelly sharing her family's gratitude after her father was awarded Birmingham City's highest civic honor, the Lord Mayor's Award, by Deputy Lord Mayor Ken Wood, on his posthumous birthday.

"The fact that he has been recognised in such a way means so much to us because he loved this city, he loved Birmingham, he was a true Brummie through and through, and to be recognised in this way, it's incredible," she said, per the Daily Mail.

During her interview, Kelly further detailed how difficult it has been losing her father, noting how dedicated he was to his craft.

"He worked so hard to do what he wanted to do most in this, and that was perform one more time, and then he was ready to go. He made a mark on this planet that will never be erased," she said.

Visibly moved to tears, the TV personality added, "It actually has been horrific. I've never ever felt anything like grief. I never realised that you could love someone so much."
