Kris Humpries’ big shot lawyers are looking to subpoena Kanye’s ex, Amber Rose, to help his case against ex-boo Kim Kardashian. Amber is currently in a relationship with another hip hop star, Wiz Khalifa.

Amber has said Kim and Kanye hooked up several years ago. This contradicts Kim, who claimed they just started mingling recently. Rose didn’t release how she knew, but she claimed to have evidence that the affair occurred. Kardashian was dating NFL star Reggie Bush when she, allegedly, first started hooking up with ‘Ye.

In an interview with Star, Amber stated:

“Kim is one of the main reasons why me and Kanye are not together. She’s a homewrecker! [Kim and Kanye] were both cheating. They were both cheating on me and Reggie with each other.”

She even claimed to e-mail Kim to try and get to the bottom of things. According to Rose, Kim never responded.

Kris is looking for $7 million in his divorce case with Kim. #payday
