Griner, an All-Star with the Phoenix Mercury, subsequently filed for an annulment of their marriage, calling their union “a huge mistake,” but an Arizona judge denied her request earlier this month.

Johnson, who has taken a year off from the court to carry the twins, told PEOPLE in a statement on Saturday that she was “thankful the annulment was rejected because an act of marriage did occur.”
“Together we made life changing decisions which impacted our lives collectively,” she added, “and we both should be held responsible for those decisions.”
