Kim Kardashian has always insisted that she and Kanye West are just friends, but that may not be the truth after all!  In an exclusive interview with Star magazine, Kanye’s ex girlfriend, Amber Rose, revealed that the reason she and the singer split was because of the reality star’s devious cheating ways.  “Kim is one of the main reasons why me and Kanye are not together,” Amber told Star.  “She’s a homewrecker!”  According to Amber, she was dating Kanye when he and Kim first hooked up — and Kim was dating NFL star Reggie Bush!  “They were both cheating,” Amber said.  “They were both cheating on me and Reggie with each other.”  Amber says it was Kim who instigated the whole affair by calling, texting and sending racy photos of herself to Kanye.   “She was sending pictures, and I was like, ‘Kim, just stop.  Don’t be that person,’” but apparently Kim didn’t care enough to respond when Amber emailed her for an explanation.
