The sighting comes after Rebel denied she lost weight using the Mayr Method diet plan.
Rebel's weight loss has been widely attributed to the strategies developed by Austrian physician Dr Franz Xaver Mayr.
However, she distanced herself from the Mayr Method in a statement on Instagram last month, telling her 10.6 million followers: 'This was never my diet.'

The Mayr Method eliminates certain foods, reduces sugar and also encourages certain eating practices such as chewing food thoroughly.
People magazine was the first publication to report Rebel had lost weight with the Mayr Method, citing a 'source' close to the actress.
The article, published in June 2020, claimed Rebel had seen 'amazing results' since adopting the method during her stay at the VivaMayr wellness centre in Austria.
