Last year, the pair made their red-carpet debut at the YES 20th Anniversary Celebration in Beverly Hills.
Ashley and Louis have been romantically linked since 2017 but have kept their relationship mostly private.
It would no surprise if Ashley chooses not to comment on the marriage rumors for some time.
Her younger sister Elizabeth Olsen didn’t confirm her marriage to Robbie Arnett for a year.
In a recent interview for SiriusXM’s “The Jesse Cagle show,” Olsen shared that they “eloped” and then held a “wedding at another time.”
She dished, “It was before COVID. I just never talked about it.”
“I had to work in England and there are visa issues with that,” she went on. “He wouldn’t have been able to come at all, actually. And also everything was so backed up. You couldn’t even, like, try to get married then. But it ended up working out.”
