A friend told PEOPLE as Wilson went Instagram official with Agruma, "Rebel's in an amazing place and I've never seen her happier."

Last month, Wilson told PEOPLE about being set up with her new partner "through a friend," though she didn't reveal who her love interest was.

"We spoke on the phone for weeks before meeting. And that was a really good way to get to know each other," she said. "It was a bit old-school in that sense — very romantic."

"I think going through the process of finding more self-worth, I think that what you want in a partner is elevated and so it's great to have someone who feels like an equal partner and be in a healthy relationship," added Wilson. "There were times — I'm not saying with all my exes, they're great — but there were some times that I was probably putting up with that I shouldn't have."

"So it feels different to be in a really healthy relationship," she said.

The actress has shared pictures and videos to her Instagram that show the two in each other's company since January. In May, Wilson posed beside Agruma, who is a fashion and jewelry designer, in a photo with friends at dinner in celebration of her latest film Senior Year.

Wilson last dated Jacob Busch, whose family founded the brewing company Anheuser-Busch. PEOPLE confirmed in February 2021 that the pair had broken up, four months after going Instagram official.
