Two pictures were shared on the official Instagram account of Kangana's team from the actor's workout session "Yaas. WHAT a transformation! Kangana Ranaut lost 5kgs in just 10 days, just in time to fit into couture," the post read.
The picture showcases the actor indulging in a rigorous workout under the guidance of celebrity fitness coach Yogesh Bhateja to shed those extra kilos.
A boomerang video was also posted on the account where Kangana can be seen doing a shoulder workout.
"The grind is real. This is what it takes to get red carpet ready for Cannes," the team wrote alongside the video.
Last year, during the 71st Cannes Film Festival, the 'Queen' actor showed off her sculpted arms and back in a see-through Zuhair Murad gown. On the second day, she wore a beaded jumpsuit from Nedret Taciroglu and played up her natural curls.
The star-studded event saw a number of Hollywood's A-listers grace the red carpet today, including Bill Murray, Adam Driver, and Selena Gomez.
