The rapper - whose real name is Curtis Jackson - has always been a musical rival of Kanye`s but now he may have ignited a bigger feud after suggesting his girlfriend is "trash". Referring to Kanye`s new song `Perfect Bitch`, which he said is about Kim, 50 Cent reminded readers that the reality TV star is only perfect in her partner`s eyes. He told XXL magazine: "I mean ┘ if that man feel like she`s perfect, then she`s perfect. He could mean it and you`ll end up singing the words to it because he`s Kanye." The rapper continued to say that what one man considers beautiful could be seen as ugly by another. He added: "You know how it is? One man`s trash is another man`s treasure." The artist - who used to date talk show host Chelsea Handler - then said he didn`t know if there was such a thing as a perfect woman. He continued: "I`m not sure. The smartest guys I know have lost being a bad judge of character in that area."
