Former NBA star Lamar Odom has revealed he used a prosthetic penis to dupe drug-testers before competing at the 2004 Olympics for the United States, according to an upcoming memoir.

The former Los Angeles Lakers star, 39, made the revelation in his autobiography "Darkness to Light", which lifts the lid on his battles with drugs and sex addiction. Odom said he had panicked after being named to the US Olympic team for the 2004 Games in Athens, fearing that he would fail a drugs test.
