With their movie and TV projects on hold due to the coronavirus, stars from both Hollywood and Bollywood have found themselves with plenty of time on their hands this year.
These celebrities appear to have used that time to transform their bodies...
Having always been candid about her body, Australian actress Rebel Wilson, 40, took to Instagram to declare: "call me: Fit Amy", a play on words from her character Fat Amy in the Pitch Perfect movies.
"I am only 3kg away from my goal weight," the star said after revealing she now works out six days a week.
"It's more about working on my mind," she told Today Extra. "I suffer from emotional eating a lot and the stresses of my job. I'm determined. So, I am trying to lose a lot of my body fat and become a healthier person. It is not so much about a number."
Alexander Skarsgard, 44, showed off an impressive pair of arms in L'Uomo Vogue, revealing that his latest transformation was for his new role in movie The Northman.
And getting prepped to play a Viking meant piling on the muscle.
"It's a real adventure movie, but it's much more. It taps into the culture, and the mysticism of the Vikings, it becomes more intimate and more personal," the actor told Vogue of the film, which also stars Nicole Kidman. "I didn't want it to be a generic 'sword-and-sandals' movie."
Indian actress Vidyu Raman, 28, has been sharing her body transformation with her fans on Instagram.
Revealing that she has so far lost more than 20kgs, going from 86.5kg to 65.3kg, the Mathu Vadalara star took to social media to write: "It's been a long & winding road. Filled with sweat and tears. When I look at the pic on the left it's surreal that I ever looked like that."
Revealing that she has turned to a low-carbohydrate diet to shed the weight, Raman has a positive message for her followers and fans: “My happiness will never be measured by an inch tape or number on the scale. I’m just focusing on being the best version of myself for there can be no happiness without good health.”
Although the Someone Like You singer has stayed tight-lipped about how much weight she has lost during lockdown, fitness experts suggest she's dropped about 40kg.
She filed for divorce from her British husband, Simon Konecki in September 2019 and has since been spotted out hiking in the hills of her newly adopted home, LA.
The Gully Boy star has wowed fans with his lockdown body transformation, going from lean to bulked up in just six weeks. Indicating that he's ditched carbs and switched to protein drinks, the Bollywood star often posts pics from the gym where he works out with a trainer. His next role will be in '83, opposite his wife, Deepika Padukone.
It's been a tricky couple of years for the Magic Mike star, which saw him split first from his wife, actress Jenna Dewan, and then from his on-off girlfriend of 18 months, British singer, Jessie J.
Alluding to the fact he'd been out of shape, Tatum, 40, took to Twitter to share a snap of his new physique and wrote: "Been a long road back. Injuries, life & insanity in general. Ha daddy's finally back boooi! Gonna be a fun next 10 year run. To all that have been there for me & held me down. Love you. Gonna make ya proud."
