Cassie took the stand this week as a star witness in Diddy’s trafficking trial and revealed several troubling details about their long relationship. One of the most disturbing claims was that her ex-boyfriend threatened to blow up Kid Cudi’s car when he found out they were dating, and the explosion did eventually happen.

Sean "Diddy" Combs is on trial. Here are the most striking revelations so far.

In 2011, she met rapper Scott Mescudi, whose stage name is Kid Cudi. At the time, she was “not in the greatest place” with Combs, and began dating Mescudi, she told a Manhattan jury on Wednesday as the third day of Combs' sex crimes trial wrapped up.
