Meanwhile, Rebel has vowed to make 2020 "The Year of Health" and it's clear she's sticking to her pledge after the Hollywood star stepped out at the Australian Open last month showing off her weightloss.
The actress has enlisted the help of renowned personal trainer Jono Castano to help her get fit.
Rebel also took to Instagram recently to show off her incredible body transformation, admitting to her followers that while she had relaxed her healthy eating habits over the festive period, she now intends to “avoid the junk and sugar food.”
"Okay so for me 2020 is going to be called 'The Year of Health' - so I put on the athleisure and went out for a walk, deliberately hydrating on the couch right now and trying to avoid the sugar and junk food which is going to be hard after the holidays I’ve just had but I’m going to do it! Who’s with me in making some positive changes this year?" Rebel wrote.
Posing in her activewear whilst out for a jog on the beach, her fans were quick to praise her.
“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.
