Ben and Jennifer announced that they are splitting in June 2015, a day after celebrating their tenth anniversary. Following the Argo actor's recent rehab stint, they finalised their divorce.

The Miracles From Heaven actress, who has three children with Ben, had opened up about her marriage's end in Vanity Fair's March 2016 issue. She said: "I didn't marry the big fat movie star; I married him. And I would go back and remake that decision."

"I ran down the beach to him, and I would again. You can't have these three babies and so much of what we had," she added. "He's the love of my life. What am I going to do about that? He's the most brilliant person in any room, the most charismatic, the most generous. He's just a complicated guy. I always say, 'When his sun shines on you, you feel it.' But when the sun is shining elsewhere, it's cold. He can cast quite a shadow."
