Showing off her slimmer figure, Rebel proved that she's well on her way to achieving her goal.
Fans were quick to praise the star for making the positive changes.
“I’m so proud of you!! You look fantastic already with your weight loss,” one said.
“You look great, you look absolutely beautiful beforehand and still now. Such a role model,” another agreed.
“You already look amazing! Killing it! Any positive changes are good changes,” another fan said.
Rebel proudly wore a figure-hugging blue dress while celebrating on New Year's Eve with royals Zara and Mike Tindall in Sydney, showing off her slimmer curves.
The actress has been training hard since 2019, after hiring celebrity trainer Gunnar Peterson, who revealed she trained at least four times a week.
“When she’s in town, she’s a solid four days a week,” the LA-based fitness expert told US Weekly. “She is such a cool person to work with.”
