The 40-year-old captioned the photo: "Lots on my mind...aghhhhhh...#single-girl-heading-to-Super-Bowl!", confirming her split from billionaire boyfriend Jacob Busch.
But how did Rebel lose more that 60 pounds after declaring 2020 as a "year of health"?
At the time, she wrote on Instagram: 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 Ive just had but Im going to do it! Whos with me in making some positive changes this year?
She revealedher target weightof 165 pounds (11.7 stone) to her fans.
Even if you have to crawl towards your goals, keep going x it will be worth it, shecaptioned a photo of herselfin a tracksuit and bra.
Try and give a little bit of effort each dayI know some days are frustrating as hell, you feel like giving up, you get annoyed at the lack of progressbut good things are coming your way," she encouraged.
Rebel previously said that she had embraced the Mayr Method as well as working out with her trainer.
She reached her goal weight in November last year.
The diet is based on the book by Dr Harald Stossier and Helena Frith Powell.
The plan focuses on your gut and how the foods you eat ultimately affect your digestive system.
Most people will just buy the book but for those with a little more cash, they will visit a Mayr centre in Austria or London.

Rebel previously posted about the centre in Austria.
Here you will spend a week having your diet and routine scrutinised by experts who will help you with your snacking and reducing gluten and dairy intake - this will cost around 1,600 for the week.
The diet is not calorie controlled but you will be taught how to chew your food and will be encouraged to eat slowly.
People following the plan will have their biggest meal at breakfast and their smallest meal at dinner time.
Its website states: "VIVAMAYR combines modern complementary medicine with traditional diagnostics and therapies according to F.X. Mayr.
"Once we have treated your condition, proper nutrition combined with exercise and improved mental awareness become the building blocks of your new life.
"Modern Mayr Medicine is based on the four principles of Rest, Cleanse, Train and Substitute with the goal of integrating and practicing each principle individually for a period of time."
Aside from diet and wellness, Rebel has also been working out with personal trainer Jono Castano.
She regularly posts videos on her Instagram stories and part of her workouts include strength building such as flipping tyres.
As well as strength exercises she also makes sure to include cardio and incorporates sprint and high intensity interval training.
She also posts about going for hikes and long walks outside.

While it's important to include all of the major food groups in your diet, Rebel recently told People magazine that she had cut down on the amount of carbs and had upped her protein intake.
She said: "Before I was probably eating 3,000 calories most days, and because they were normally carbs, I would still be hungry.
So, I've really changed to eating a high-protein diet, which is challenging because I didn't used to eat a lot of meat. I eat fish, salmon, and chicken breast.

While Rebel has overhauled her image, she also said that she won't restrict herself and added that "nothing is forbidden".
She said she will still have take-out but that she might just eat half or have a smaller portion than she previously would have.
Rebel has also previously talked about emotional eating and said that food was something she used to cope with becoming internationally famous.
She added: "There is a lot of stress that comes with it, and I guess my way of dealing with it was just eating donuts."
