The Alleged Jumpoff: Brittney Jones
The Celebrity: Ashton Kutcher
The Scandal: About a year before he split from his wife of six years, Demi Moore, Jones told Star that she had had sex with Kutcher while Moore was out of town shooting a movie in September 2010. Kutcher denied it, but he was caught cheating with another woman in late 2011 and subsequently split up with Moore.
