The most shocking celebrity transformations of 2023

Stars often change their looks, swapping hair colours or styles and embracing new trends as soon as they come along. Here we look at some of the biggest changes spotted amongst our favourite stars.

Kelly Osbourne

Reality star Kelly Osbourne, 39, has confessed that she's taken her post-baby weight loss a little too far.

"[I was] "on a mission after having the baby to lose all [my] baby weight," she told the podcast Scheananigans.

"Then I was like, 'Well, I lost all the baby weight. Let’s see how far I can go with it.' And then went a little too far."

While she has admitted to trying Ozempic for a short time, she revealed that the majority of her 85lb (38kg) weight loss happened once she stopped using it.

Sharon Osbourne

And it's not just Kelly. People have been shocked at her mum Sharon Osbourne's gaunt appearance lately after she admitted losing 14kg with the help of the controversial weight loss drug Ozempic.

"It’s just time to stop, I didn’t actually want to go this thin but it just happened," Sharon, 71, explained on Piers Morgan's Uncensored show recently, adding, "I'll probably put it all on again soon."

Social media users were shocked by Sharon's new look, with one user simply writing, "Sharon's face!"

"Sharon has lost LOTS of weight," another added.

Zac Efron

Movie star Zac Efron's appearance at the premiere of his new wrestling film The Iron Claw had people wondering once again why he looked so different but the actor has actually addressed his facial changes before.

Last year Zac, 36, told Men's Health that he had shattered his jaw after falling over while running in his house and breaking it on a granite fountain.

He told the magazine that in recovery, his masseter muscles overcompensated.

"The masseters just grew,? he revealed. "They just got really, really big."

Jessica Simpson

Actress Jessica Simpson has often been criticised for her transformations over the years but her recent 100lb (45kg) weight loss after the birth of her third child had fans worried.

"You should put some weight back on. Looked healthier that way," one said on her socials while another pointed out: "Your [11-year-old] daughter is bigger than you."

But Jessica, 43, addressed her weight loss by talking to Bustle earlier this year and denying she had used weight loss drug Ozempic.

"Oh Lord. I mean, it is not [Ozempic]," she told the magazine.

"It’s willpower. I’m like, do people want me to be drinking again? Because that’s when I was heavier. Or they want me to be having another baby? My body can’t do it."

Mindy Kaling

Another weight loss transformation has been The Office and The Mindy Project star Mindy Kaling.

But she told People magazine that it was down to hard work. "I know people are really interested in my body and the changes in my body, and I think it's flattering and sometimes it's just a little much, so I don't try to tune it in too much," Mindy, 44, revealed.

"The truth is that I spend so much time and energy trying to be healthy.

"I just tell myself I have to do basically 20 miles a week of either hiking or running. And so that's been incredibly helpful to me," she adds.

Pamela Anderson

Former Baywatch star Pamela Anderson's make-under caused headlines this week. The actress has stopped using heavy make-up and fans are praising her for her fresh new look.

"Love your freckles! Hidden all these years under makeup? So glad you are connecting to your inner self! Looking better than ever!" one person wrote on one of her Instagram posts.

"I love your new look! You are such a natural beautiful!" another commented.

Pamela revealed that the change was after her make-up artist, Alexis Vogel, passed away from breast cancer.

"She was the best. And since then, I just felt, without Alexis, it’s just better for me not to wear makeup," she told Elle.

Liam Payne

Boyband singer Liam Payne has looked the same for years and then suddenly this year he looked different. Liam, 30, surprised fans when he had a well-defined square jaw at the All Of Those Voices UK Premiere in London in March.
