Rebel Wilson looks almost unrecognizable at the premiere of new Netflix movie Senior Year

Funny woman Rebel Wilson turned a lot of heads at the premiere of her new Netflix movie, Senior Year, earlier this week in Los Angeles.

Rebel, who recently shared why she lost weight after her 'Fat Amy' role, donned a beautiful custom green sequin Jason Wu gown with a plunging off-the-shoulder neckline. She paired the dress with emerald green heels at the red carpet event. 

The 42-year-old actor looked amazing, clearly reveling in her fit physique.

Fans were able to glimpse at Rebel's new look when the trailer for Senior Year—her first new movie in three years—first dropped last month. 

In the new R-rated comedy, out on May 13, Rebel plays Stephanie Conway, a high-school cheerleader who suffers a head injury and falls into a coma before her senior prom. She wakes up 20 years later as a 37-year-old woman who decides to head back to high school to finish her term. Rebel plays the older Stephanie, who is portrayed by Angourie Rice as a teenager.

Fans took to social media to compliment Rebel's outfit. "Flawless, timeless movie star," a user commented on a photo from the premiere that Rebel herself posted on her own Instagram account. 

Someone else commented, "My little girls and I saw you walking into the elevator last night on your way there and I wanted so badly to say I LOVE YOU REBEL, YOU LOOK STUNNING! 😘 My 3 year old said you looked just like a beautiful mermaid! 🧜‍♀️ 💚"

"You look great in green," yet another fan wrote.

Given Rebel’s obvious body transformation, fans have been wondering about the actor's diet and exercise routine. In an interview with Apple Fitness+ back in January, the Australian actor revealed how she lost "unwanted body fat,” specifically mentioning a low-impact exercise that she partook in every day for an hour.

The Pitch Perfect star's secret? Walking for a solid 60 minutes every single day.

"The doctor said to me, 'Rebel, the best way for you to lose unwanted body fat is just simply walking,'" the actor said in the interview. "'Doesn't have to be high-intensity, doesn't have to be uphill, just moderate walking an hour a day.'" The effort clearly paid off.
