Meg Ryan
Dennis Quaid and Meg Ryan were quite a cute married couple, once upon a time. That was until Ryan began working on the set of the film Proof of Life, however. It was there that she met Russel Crowe, and their on-screen chemistry translated into the real world only too well. Quaid would not stand to be cuckolded, of course, and broke things off with Ryan, legally. Crowe, on the other hand, was involved with Danielle Spencer.
Kobe Bryant
We hate to sully the late legend’s name, but Kobe Bryant was embroiled in quite a disturbing incident. Bryant was accused of sexual assault by a concierge of a hotel that he stayed at. The two clearly had sex, and not the most pleasant kind. While the evidence was rather ambiguous at the time, Bryant ended up winning the case, and returned to his spouse Vanessa unscathed, with who he remained until he tragically passed away in 2020.
