Earlier this month, Rebel revealed that despite going public with Jacob in September, she’s actually known him for much longer. 

Giving a rare glimpse into life with her ‘very private’ partner, the actress, 40, briefly spoke about their romance during a Q&A session on her Instagram page.

Rebel said she actually met him before she started her health journey at the beginning of this year, which saw her drop an incredible 30kg.

‘He’s a very private person, so I don’t like to give away too much in that department,’ Rebel said. 

‘But I will say we dated before I started any of this health journey, as well as now. So that goes to show you, ladies: you don’t have to be a certain size to get a boyfriend.’

Rebel and ice cream founder Jacob apparently first met in 2019 and made their red carpet debut at a glitzy gala in Monaco in September.

Elsewhere during the chat, Rebel said that she has made the decision to freeze her eggs because it seemed like a ‘pretty good time to do it’. As she revealed her hopes to have children in the future.

Rebel has been on an incredible health and fitness journey this year, losing a staggering 30kg.

Just last month, she proudly announced on her Instagram Stories that she had reached her goal weight of 75kg (165lbs or 11.8 stone) – sharing a photo of the number 74.6 on the scale.

The Pitch Perfect star said that while it’s not about a number, she needed a ‘tangible measurement’ to keep her motivated.

‘Hit my goal with one month to spare! Even though it’s not about a weight number, it’s about being healthy, I needed a tangible measurement to have as a goal and that was 75 kilograms,’ Rebel captioned the post. 

According to People magazine, Rebel’s remarkable transformation is partially down to following the Mayr Method diet plan.

‘It’s an approach that eliminates food intolerances, reduces sugar, encourages eating whole foods slowly, boosts the immune system and reduces inflammation,’ a source said.

‘She exercises with a personal trainer up to six times a week, goes on walks and is trying to up her protein intake nutritionally.’
