Amber Rose -- I Forgive Kanye West for Banging Kim Kardashian

Amber Rose says she's totally forgiven Kim Kardashian for allegedly hooking up with Kanye West behind her back ... and says she feels bad for calling Kim a "home-wrecker."

Amber's referring to a recent interview ... in which she claims Kanye and Kim had a secret affair while she was still dating the rapper a few years ago. Sources close to Kim tell us Kardashian vehemently denies ever getting intimate with Kanye.

But last night, Amber was out in L.A. -- and told our photog, "I actually feel bad that I called [Kim] a homewrecker ... 'cause that was kind of mean."

"I forgive her ... and I forgive Kanye too ... it's not a big deal, you know?"
