Kim Kardashian’s claims that there is nothing between her and Kanye West were blown out of the water today when Amber, the rapper’s ex-girlfriend, said his affair with the reality TV star led to their split.

Amber, 28, also claimed that Kim Kardashian was seeing NFL star Reggie Bush at the same time as she was seeing Kanye West – who was in a serious relationship with Amber at the time.

In an interview with Star magazine, Amber said Kim Kardashian, 31, was one of the main reasons she and Kanye West, 34, broke up.

Amber said: “She’s a homewrecker! They were both cheating. They were both cheating on me and Reggie with each other.”

Amber also said that Kim Kardashian instigated the affair by sending sexy pictures of herself to him as well as calling and texting him.

“She was sending pictures, and I was like, <<Kim, just stop. Don’t be that person>.”

Amber said she also emailed Kim Kardashian asking her for an explanation but was disappointed not to get a reply.

Amber said: “I thought at least she’d be woman enough to respond to me. She never responded.

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

Amber does thank Kim Kardashian for helping her find true love in the arms of rapper Wiz Khalifa, 24.

Amber explained: “I want to thank her. Because if she was never a homewrecker, then I never would have met Wiz, and I wouldn’t be as happy as I am now.”

Amber’s claim comes a few weeks after Kim Kardashian and Kayne West were spotted together at a party in New York and Kayne was “all over” her – just a month after she filed from divorce from husband Kris Humphries.

In November, she hinted that the pair may have at one time been more than friends when asked on the Wendy Williams Show if Kim and Kanye.

“I mean, Come on, like, you know,” she laughed. “Come on! We’ll keep it cute.”

A source told The New York Daily News: “Kanye was eating Kim up like she was a piece of cake. He was all over her – caressing her head, touching her waist.

“I think he was dying to kiss her, but there were too many people in the room.”

Kim Kardashian and Kanye West, who are long time friends, were attending billionaire Ron Burkle’s party for Kanye and rapper Jay-Z who performed tracks from their hit album at LA’s Staples Centre.

Last year, Kanye West made an appearance alongside a flirty Kim Kardashian on the first season of reality show Kourtney & Kim Take New York.

And earlier this year, they filmed a Star Wars inspired skit together for U.S. network Comedy Central.

However, a source told People last year that Kim Kardashian and Kanye West are “just friends”.

“There is nothing going on romantically,” the insider said.

“Kanye and Kim are just friends and have been forever.”
