She captioned the post, “So proud of these three glorious girls, it’s an honour being their mummy…feeling incredibly lucky today #happymothersday.”
Dornan proposed to Warner back in 2012 and tied the knot in an intimate ceremony in 2013. They are also parents to two daughters, Dulcie (5) and Elva (3).
Shortly after announcing baby number three, Dornan appeared on an episode of Jimmy Kimmel Live!, where he joked that their new addition might not be their last.
“Part of me feels like [I need] to put a cork in it after this,” he said. “But then alternatively, I feel like we make really great kids. I may just—if my wife’s willing—do it until we can’t do it anymore.”
Sounds like something Christian Grey would say.
