Borussia Dortmund ace Mohamed Zidan has revealed that he has been married to Stina Rohde since 2006, but kept their marriage quiet. The Egypt forward has always referred to the Danish blonde bombshell as his 'girlfriend', often drawing sharp criticism in Egypt. After Stina gave birth to a baby boy, Adam, Zidan faced a baptism of fire as sex outside wedlock is punishable and sinful in the Arab world. However, the 29-year-old footballer was quick to state that he and Stina had tied the knot long ago, saying he always abides by Islamic doctrine. "I'm a devout Muslim and would never be in a relationship with a woman without marriage," he told FilGoal.com yesterday. "It's not true that I hook up with girls as some sports websites claim without knowing the truth. "The fact that we didn't have a wedding doesn't necessarily mean we didn't get married. Stina is my wife in accordance to Islamic principles. We just threw a small party to celebrate our marriage in 2006. Only close friends and family attended it." On why he was keeping his marriage a secret, Zidan said: "Pursuant to German law, if a couple divorce, the woman gets half of the man's wealth. For this reason I postponed the announcement of our marriage in Germany and Egypt as well." Last year, Zidan got engaged to Egyptian actress Mai Ezz el-Din after allegedly breaking up with Stina. But his engagement to the Egyptian actress broke off after several months, before he got back together with his old partner. "Two years ago, Stina and I separated. I then got engaged to Mai Ezz el-Din," the former Werder Bremen man explained. "I and Stina made up one year and four months ago. We have been together ever since. "She's the mother of my child now and that's a whole different story. She will officially be my wife in Germany, not just in Egypt."
