Rebel Wilson flaunts weight loss after attending Monaco art exhibit with new boyfriend Jacob Busch

Rebel Wilson, 40, flaunted her incredible 18kg weight loss in a short Boomerang clip via Instagram on Sunday. 

After attending an art exhibit at the Villa Paloma Monaco in Monte-Carlo with her new boyfriend Jacob Busch, 29, the Australian comedian took to Instagram with a video of herself twirling on the balcony. 

Flaunting her recently slimmed-down physique, the blonde played up to the camera a form-fitting fuchsia frock with a flirty V neckline. 

With her locks styled in a bouffant bun and a sultry coat of make-up, Rebel looked every inch the Hollywood bombshell.  

Rebel has been on a health and fitness journey this year, losing at least 18kg (40lbs or 2.8 stone).

Elsewhere at the art exhibition on Sunday, Rebel and Jacob met with Prince Albert of Monaco. 

Rebel posed up a storm with the 62-year-old royal when appearing at the art event for renowned Spanish painter Joan Miró.

The beauty made her red carpet debut with Jacob at a gala in Monaco this week. 

While the Isn’t It Romantic star and the beer heir held back on any public displays of affection, they are reportedly ‘officially boyfriend and girlfriend.’ 

‘He’s a gentleman, has very old school manners and treats her well,’ a source told People of their relationship dynamics. 

‘He is also very health conscious and they’ve been motivating each other with their health journeys,’ they added.

Jacob’s family founded the Anheuser-Busch brewery, which produces America’s most popular beer, Budweiser. 

In 2016, Forbes listed the Busch family as the 16th richest in America, with a fortune of US$13.4billion.

While it’s unclear how much of that will be inherited by Jabob, his current personal net worth has been estimated at US$100million.

At one point, the family even owned their own elephant named Budweiser. 

In 2017, the young entrepreneur launched his own beer called Sons Beer with best friends Carlo Mondavi and Elliott Taylor.

Despite branching out on his own, Jacob is still very much involved with his family’s charity, the Busch Family Foundation, which benefits the Busch Wildlife Sanctuary, the Cystic Fibrosis Foundation and The Boys and Girls Club.

Jacob and Rebel’s 11-year age gap shouldn’t be a problem for the 29-year-old, who previously dated Real Housewives of Beverly Hills star Adrienne Maloof, 59.
