Australian actress Rebel Wilson has shown off her knock-out figure in a white tennis outfit.

The 41-year-old shed more than 66lbs during her ‘Year of Health’ last year and looked incredible in her latest Instagram post.

Rebel shared a video of her at a tennis-themed event at the Los Angeles home of renowned American interior designer Kelly Wearstler.

She appeared happy and healthy sporting a white polo shirt with a matching pleated miniskirt, visor - with Rebeldon emblazoned across the front - and trainers.

In the video, the Pitch Perfect star showed off her tennis skills with an impressive serve.

At the end of the clip, she threw her arms up in the air with delight - obviously pleased with her performance.

Rebel also posed for photos with fellow Aussie tennis player Rennae Stubbs and singer-songwriter Amy Shark.

And in another snap she was drinking out of coconut - no doubt to cool off after all her hard work.

Thanking her host for the experience she posted: "Aussie! Aussie! Aussie! Thanks @kellywearstler for having us at your gorgeous house x."

Rebel's uplifting pics sent her fans into a frenzy, who commented on how well the actress looked.

One wrote: "Holy moly you're so fit! Well done!"

Another said: "Wowww you look amazing, my role model."

While a third gushed: "You look amazing and so happy."

Rebel recently showed off the results of her weight loss at a football game in Los Angeles.

The actress shared a snap of her at the NFL game to cheer on the Los Angeles Rams as they took on the Chicago Bears at the SoFi Stadium on Sunday.

“Let’s go boys! @rams All the way to the Super Bowl,” she wrote, alongside yellow and blue heart emojis.

In the pic, Rebel looked stunning sporting a blue and yellow Rams jersey looking years younger than her age.

“Damn girl, great job on the weight loss," one of her followers commented on the photo, while another added: “Whoa girl you look like a whole new you!"

Rebel decided to lose weight as she embarked on a Year of Health in 2020 when she turned 40.

She dropped an impressive 30kg (66lbs), but said losing weight was never a priority.

Instead she wanted to change her lifestyle in order to get fitter and healthier.

"The goal was never to be skinny," she told Shape magazine. "It was never to fit into a certain dress size. I put in a weight because I needed some tangible thing."

"I never properly considered wellness from all angles. But I was turning 40 and thinking about freezing my eggs, and the experts told me that the healthier I am, the better the process can go."
