Kim Kardashian cheated on Reggie Bush with Kanye West
The real reason Kim Kardashian and Reggie Bush broke up is because she was cheating on him with Kanye West. Supposedly, Reggie was ready to settle down and even bought an engagement ring for Kim, but that all came to a screeching halt.
Reggie is rumored to have been on her computer one day when West started sending her instant messages and Bush pretended like he was Kim. Through the conversation, Reggie deciphered that they were hooking up with each other and when he confronted Kim she admitted it all. That’s when Reggie called things off and left her.
