Wilson — who welcomed her first child, daughter Royce, via surrogate back in November 2022 — announced she was in a relationship with Agruma, founder and owner of the athleisure brand Lemon Ve Limon, that June.

The actress recently told PEOPLE that she was "shocked" at "how deep the connection was and how instant it was" when she met Agruma, as she had thought up until that point that she "was really looking for a husband" — to the point where she "[dated] about 50 guys in one year to try to catch up on the dating experience."

"I always was a bit of a girls' girl and had deep friendships with women, but this was the first time that it was a romantic connection and I was just shocked," Wilson, who is launching a new dating app called Fluid, recalled.

She added: "And then I was like, 'Oh, well, what if that was just part of my personality that I was repressing and wasn't exploring?' And maybe I should have 10 years earlier. My journey is what it is, but it's just awesome now to be in a relationship."
