The reality TV star loves the rapper's new song, "Perfect B--ch," and having a fashion-obsessed boyfriend: "I think it's essential to have similarities."

Kim Kardashian's new boyfriend Kanye West loves his lady's curves so much that he has written a sweet song in their honour, a little ditty entitled Perfect B**ch.

And while the lovebirds were in Hawaii, often seen wearing matching outfits, Kim revealed just why her rapper lover is so besotted with her bodacious bod.

In a photo she posted on her Twitter, the reality star smiles at the camera -- presumably held by Kanye -- as she walks away, showing off her shapely rear. Hard to believe that this is the buttocks her former BFF Paris Hilton once called “cottage cheese inside a big trash bag," and the rear Kim actually had X-rayed in the third season of Keeping Up With The Kardashians to prove that there were no implants hiding in there.

But be not deceived. Theirs is not just the passing sizzle of intense sexual attraction. Kim and Kanye also share a powerful love of fashion.

Kanye has far more fashion cred than Kim. After all, he got Vogue editrix Anna Wintour, stylist/editor Carine Roitfeld and designer Olivier Theyskens to attend his first Paris runway show when he debuted his women’s collection last fall. But Kim's clothing ventures, while extremely mainstream (hel-lo, Sears), are far more profitable. But he was invited to the recent Met Gala and rumors are that Kim was denied because Wintour can't abide her.

Kim recently told New York Magazine about her powerful fashion connection with her new boyfriend. 

“If I have a design meeting, or he has one, we come back and talk about how our meetings went. It’s cool, ’cause you can definitely get more in-depth with someone who actually knows what you’re talking about... I think it’s essential to have similarities. When this whole life is done, and it’s just the two of us sitting somewhere when we’re 80, you want to have things to talk about that you have in common. I think that’s something maybe I didn’t value as highly as a quality I cared about in someone.” 

We're having a little trouble picturing Kim and Kanye at 80, sitting around the dining room talking about the value of ready-to-wear over a luxury line. But never say never, right?
