Model-turned-actress Brooke Shields says that soon after her marriage to former tennis star Andre Agassi, she realised it was a mistake. The actress and Agassi split in 1999 after being married for two years, but Shields feels she always had relationship doubts, reports femalefirst.co.uk. “It hit me all of a sudden – I knew I had made a mistake. For the next two years we saw very little of each other. I was working on my show, ‘Suddenly Susan,’ and he was playing at various tournaments. “He alienated me when he lost and was on to the next tournament after he won. We were drifting apart,” she wrote on her biography. Andre confessed he’d been “addicted to crystal meth” since their dating life began, but she says she had always hoped to work things out. “I was the one who had supported him unconditionally when he told me (after we started dating) that he was basically bald and had been wearing hairpieces most of his adult life. Why would this have been any different? I would have been his biggest advocate and supporter,” she shared.
