The Pitch Perfect star gave fans the inside scoop on her relationship with the Napp's Dairy Free Ice Cream founder. In a new Instagram photo, Rebel and Jacob don matching sunglasses while posing for a selfie in front of the water.
Alongside a cheeky wink emoji, the 40-yer-old star captioned the picture, "We do a lot of exercise together."
When Jacob commented on the post with a heart and strong emoji, Rebel replied with a kiss. Killing Eve star Jodie Comer also commented on the couple's photo with a "hell to the yes."
Rebel and Jacob, who hails from the Anheuser-Busch brewing dynasty, first sparked romance rumors in late September during a trip to Monaco. In a photo posted to Instagram on Sept. 24, Rebel could be seen getting cozy with the businessman before embarking on a helicopter ride with Helen Mirren and Kate Beckinsale.
Then, later that same day, the couple made their red carpet debut at the Monte-Carlo Gala For Planetary Health, with Rebel taking to social media to post photos from the event.
"So happy to have raised over 1 million euros for the auction lot I helped with at the Monte-Carlo Gala for Planetary Health for HRH Prince Albert II's foundation that does such great environmental work especially with our oceans - removing micro plastics and regenerating coral reefs," she wrote. "Ps I really wanna spend a week on Serenity the gorgeous super yacht that was generously auctioned off!"
