Rebel Wilson has been teasing fans with glimpses of her three-stone weight loss.

And now, the Australian actress, 40, unveiled her shrinking frame in full as she slipped into a form-fitting blue dress as she attended a fundraising event for The School Of St Jude – an education establishment in Tanzania that gives free education to intelligent kids in Arusha – on Wednesday.

Sharing a snap ahead of the charity event, the Pitch Perfect star appeared remarkably slimmer in a cobalt blue garment that showcased her tiny waist and full bust.

Rebel looked every inch the confident beauty as she posed up a storm in the offering, which she captioned: “Raising money for a good cause today @schoolofstjude with the help of two hot Jacobs @jacobandreou & @jacobpbusch x Hair & photo: @robertvetica Make-Up: @makeupmatthew Styling: @elizabethstewart1 Dress: @alexevenings.”

Proving that the snap was a hit, a number of kind words were typed in the comments section.

One person gushed: “Sweet baby Jesus!!! You look amazing.”

A second added: “Look at this super model!”

Others echoed: “Hellloooooo hottie!!!!” and “You look so HOT!!!”

Rebel launched her lifestyle overhaul back in January 2, telling fans 2020 was going to be her “Year of Health”.

Since then, she’s lost a whopping three stone by overhauling her diet to include way more fibre.

She is working out with a personal trainer six times a week and going for plenty of walks and hikes.

The star also makes sure she gets at least 10,000 steps in every day and is tackling her gut health with the Mayr Method diet plan.

Rebel previously told the Mirror that she wanted to transform her body in a bid to land more roles.

She said: “I literally feel as if I have to physically transform because it’s very difficult for people to imagine [me in serious roles] for some reason – even though we’re in a very imaginative industry.

“I feel that I physically have to show you that I am different and I am transformed in order to help transform my career.

“I still love comedy, but I did train originally as a dramatic actress which people forget.”
