Janet Jackson wanted Tupac Shakur to take an AIDS test before a kissing scene in their 1993 movie, Poetic Justice, a new book claims. In his biography, Only God Can Judge Me: The Many Lives of Tupac Shakur, biographer Jeff Pearlman recounts on-set hostilities between Jackson, 59, and the late rapper, including an incident that took place before the two stars were due to film an intimate scene. "S*** hit the fan late in the process, when it was time to film a kissing scene," Pearlman writes in the book, an excerpt of which was published by The Hollywood Reporter on Monday, October 20.
