"Ant and I have made the difficult decision to separate,” the mom-of-three, who also shares son Brayden James, 6, and daughter Taylor Reese, 11, with her ex Tarek El Moussa, captioned a snapshot of herself walking along the beach with Anstead, 43. "We are grateful for each other and as always, our children will remain our priority. We appreciate your support and ask for privacy for us and our family as we navigate the future."
At the time, they were granted joint legal and physical custody of Hudson.
In January 2021, Anstead revealed that he and the blonde beauty, 38, were getting along just fine. "There's never been a scenario where I've asked for him and not had him and vice versa," he said of their tot.
The Flip or Flop alum was apparently "anxious" to beat Anstead down the aisle, OK! previously reported. "She never saw that coming, and it bothers her to no end," an insider shared.
"Josh is a great father figure to her kids, and they’ve been talking about starting a family of their own even before they got engaged," the source added.
