People reports that the whole thing went down during a very intimate ceremony at a friend's house in New York state. Apparently, only their child, Malcolm, and one other witness were in attendance.
John and Olivia have been together for a minute now. Their relationship was officially public after it was revealed that the former was divorcing his ex-wife, Anna Marie Tendler, after nearly seven years together.
They welcomed Malcolm together in November of 2021, and ever since a since-deleted Father's Day post from John showcased a ring on his finger, there's been speculation that they recently got hitched.
Now, it seems like that speculation is confirmed. BuzzFeed has reached out to both stars' reps for further comment, but don't hold your breath on hearing anything more about the subject for a while — in terms of public statements about their relationship, John and Olivia are pretty tight-lipped, presumably for reasons which anyone who's been on social media at all in the last several years can understand.
