Rebel Wilson made her red carpet debut with her rumored boyfriend Jacob Busch.

The 40-year-old actress looked so stunning while attending Prince Albert’s Planetary Health Gala in Monaco alongside the businessman, 31, earlier this week. In photos taken on the red carpet, Wilson flaunted her visibly slimmer figure in a form-fitting, off-the-shoulder metallic evening gown, while posing besides her rumored beaux, who wore a classic black tuxedo for the outing. The Pitch Perfect star was all smiles with Busch, who held her close by his side.

It’s the first red carpet appearance Wilson has made since she embarked on her "year of health" weight loss journey, which she’s been documenting on social media during the ongoing coronavirus pandemic. (It's been reported that she's lost an estimated 40 pounds as yet.)

“They are officially boyfriend and girlfriend,” a source told PEOPLE about the duo. “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 new couple seemingly confirmed their romance just a few days ago after Wilson and Busch appeared together in a group shot with actress Helen Mirren and friends. “Quick Helen, get to the chopper! #TeamMonaco,” Wilson captioned a picture on Instagram showing her wearing a green sweater while embracing her new man. The pair also appeared smitten in another snap via her Instagram Stories, which featured Wilson dressed in the same outfit as her boyfriend posed shirtless.

As fans know, the Bridesmaids entertainer was previously involved with comedian Mickey Gooch Jr. in 2015, and later with stuntman Aden Stay in 2017.
