Rebel Wilson’s personal trainer Jono Castano is spotted with Rita Ora

Jono Castano has made a name for himself as Rebel Wilson’s go-to trainer. 

And on Wednesday, it appeared the Sydney fitness guru had his eye on another major celebrity who is spending time in Australia.

The former soccer player socialised with British singer Rita Ora after her Nova Red Room performance, later posting a photo of the pair on Instagram.

Jono seemed to be making a joke as she stood next to the Bang Bang singer, alongside his stylishly dressed wife, Amy. 

‘When I see sausage rolls backstage,’ Jono captioned the post.

Rita looked glamorous in a strapless top, baggy pants and high heels.

She styled her hair in braids for the performance.

Jono has become known in celebrity circles for his work with Rebel Wilson, who lost a great deal of weight last year.       

In November, Jono revealed the secret to their workouts was making sure to laugh. 

‘I love a bit of banter. It makes the session more enjoyable when people bounce off one another,’ he told news.com.au. 

‘You’ve got to enjoy coming to training. Most people don’t enjoy getting shouted at, that’s not what training is about. Rebel and I had a good laugh, so many laughs.’   

Jono added that he believes in having treat days, saying: ‘I’m all about balance.

‘When people hear the word “diet” they get turned off and think they have to completely change their lifestyle. It’s not about that.

‘It’s about enjoying your treats. You can still go out for drinks with your mates, as long as you’re back on track the next day.’

Earlier this year, Jono appeared on Channel Seven’s Sunrise, where he ran the hosts through Rebel’s workout routine. 

He first demonstrated weighted bicep curls, before moving on to shoulder presses.

The former soccer player-turned-weight loss expert explained that he uses both these exercises while training with Rebel.
