Amber claims she was dating Kanye when he and Kim first hooked up — and Kim was still dating Reggie!

The hip-hop community shed a big, bald tear when Kanye West and Amber Rose broke up in 2010 — but is it possible Kim Kardashian is to blame for the whole thing? “Kim is one of the main reasons why me and Kanye are not together,” Amber tells Star magazine. “She’s a homewrecker!”

Amber paints a pretty shocking story, claiming that she was dating Kanye when he first got together with Kim. And to make matters even worse, Kim was still dating Reggie Bush!

She says “they were both cheating,” and it all began when Kim started sending Kanye sexy pictures of herself. Amber even e-mailed Kim to get her to stop, but she says Kim never wrote back.

“It’s very important that us women stick together and we don’t f**k each other over like that,” Amber tells the mag.
