Amanda Wyatt, 23, has told how the hunky singer repeatedly cheated on the Oscar winning star in the run-up to their all-star wedding last summer. The blonde lingerie model alleged that while the couple were busy making plans to marry, ex-junkie Urban, 39, would make passionate love to her during secret meetings. She claimed to a Uk newspaper the cheating music idol Urban: * NEVER used protection * BEDDED her in the gym and bedroom of the sprawling Nashville, Tennessee, mansion the star now shares with Kidman. * BOMBARDED her with sleazy text messages begging her to come round for sex sessions while the A-list actress was out of town. * ROMPED completely naked with her in his swimming pool during a wild house party. * DROVE himself to the brink of despair with drug use. Amanda's bombshell claims will devastate Kidman, 39, who has recently been a rock for Urban after he voluntarily entered the Betty Ford rehab center in California. Now speaking for the first time about their alleged secret affair, Amanda revealed how she was regularly sleeping with Urban even after she saw pictures of the engaged celebrity couple splashed across magazines. And she insisted she now wants nothing more to do with him and has promised Kidman she is not a threat to her marriage. The pair were linked again by a US magazine in October being intimate just about the time he went into rehab. "I'm sorry if I hurt Nicole but I just want to tell the truth and move on," Ms Wyatt told Britain's The Mail on Sunday. "I hope that she finds happiness with him but Keith is a deeply troubled man. "I hope for her sake that he sorts himself out. She deserves better." Wyatt said she continued to see Urban regularly even after finding out of his burgeoning romance with Kidman in mid-2005. "I guess I knew he was seeing her but he was also seeing me," Wyatt said. "He wasn't married so I still held out hope that they were just having some kind of publicity relationship. "You have to understand, Keith was a star and I was a nobody, but even by his standards Nicole was a superstar." Wyatt says their sexual relationship lasted long after he began seeing Kidman. "When we made love he never used protection," Wyatt said. "He told me that he liked that I didn't pressure him to get married or have babies. "I sometimes wonder if he said the same thing to Nicole. "I never wanted to trap him. "I tried not to fall in love with him but we were together throughout the whole time he was dating Nicole and engaged to her, right through 2005 and to around May 2006. "Whenever he was in town we'd see each other two or three times a week. "We'd drink and party and make love and (were) constantly on drugs." Wyatt said Urban had been misleading his own family about his substance abuse. "He drank constantly - his favorite was Crown Royal Reserve whiskey - and he did drugs. Ecstasy, cocaine, pot - you name it," Wyatt said. "He told me he'd been in rehab for cocaine and when his mother was there from Australia she was very protective of him. She kept telling me it was okay for him to drink but begged me not to let him do cocaine again. I didn't dare tell her the truth - that he was still doing it. "Looking back, I rarely saw him sober. He'd work during the day but the bourbon would be flowing and, at night, he'd take ecstasy and coke. We partied constantly." Click here for the sexy pics!
