Looks like Tristan wasn't the only one with fidelity issues in the relationship! According to a source, Khloe cheated on Tristan with her ex French Montana months ago! Apparently, she wanted revenge.
Khloe and French Montana dated for a year back in 2013 but she allegedly turned to him while she was going through public issues with Tristan. And apparently Khloe's sisters Kim and Kourtney support it! They must REALLY hate Tristan!
Doesn't Khloe know that two wrongs don't make a right?!
