It was revealed that the Pitch Perfect actress had struck up a romance with entrepreneur Jacob, after the couple made their red carpet debut at Prince Albert’s Planetary Health Gala in Monaco last month.

Jacob – whose family founded the Anheuser-Busch brewing company in 1852 – is even said to be helping Rebel in her ‘health journey’ as they are both striving to lose weight.

A source told People magazine: ‘They are officially boyfriend and girlfriend. He’s a gentleman, has very old school manners and treats her well. He is also very health conscious and they’ve been motivating each other with their health journeys.’ 

The insider added: ‘Now she’s making it official by making her red carpet debut with him at the Planetary Health Gala in Monaco and attending a private dinner with Prince Albert hosted by Isabelle Bscher and Galerie Gmurzynska.’

Meanwhile, Rebel recently said men often get ‘intimidated’ by her because of her comedic career, so the actress is no doubt thrilled she’s found love with Jacob.

‘I feel like I’m the nicest, most down-to-earth person. But you can see it in their eyes, they get very intimidated. And I don’t know why. Do they think I’m gonna make a joke about them at the BAFTAs or something? I don’t know,’ she said to the Independent in June.

‘I think the psychology behind it is that comedy is power. If you’ve got the ability to make people laugh, you have an inherent sense of power with that. 

‘And sometimes men feel uncomfortable with women having that. But of course, women have always been funny and talented. Maybe that’s scary.’

And Rebel said funny men are ‘never interested’ in her, something which she finds really bizarre.

She added: ‘I’ve come across a weird thing romantically. I’ve often been interested in funny men, but funny men are never interested, romantically, in funny women. 

‘Never. And I don’t quite understand, because people always say they value a sense of humor in a person, but yet when a woman is funny.’
