The notoriously private rapper, who just last week proposed to the mother of his four-month-old baby North West, is clearly living on cloud nine.
"Kim is definitely not around me to be famous and I'm not around her to be," said Kanye, speaking on On Air with Ryan Seacrest.
"I’m around her because she’s awesome and she looks amazing and she’s a sweet person. It's an unfair level of awesomeness in one person to be that smart, to be that nice, to be blatantly fine as hell.
"Like, one of the most beautiful people of all time. She's not hard to wake up to."
The naturally confident Kanye admitted to feeling nervous about his extravagant proposal, which took place on Kim's 33rd birthday at the AT&T Park in San Francisco, in front of Kim's family and friends.
"I was nervous," said the 36-year-old rapper. "I was talking to her cousin. I was like, 'I don't know, what do you think she’s going to say?'
"I'm not arrogant about love and feelings at all. I'm confident in the work I put so much work into, but this is someone else's feelings. You never know what someone else may feel at the time.
"I just knew I wanted her to be my girl for a long time. I remember I saw a picture of her and Paris Hilton and I remember telling my boy, 'Have you seen that girl, Kim Kar-dijon?'"
Apart from asking Kim's mother, Kris Jenner, for permission to marry her daughter, Kanye kept his proposal a secret.
"I just didn't tell anybody," said the new father. "Everybody that came in just thought it was a surprise party. So of course I didn't tell her that anybody was coming in and she knew I was going to do something for her birthday.
As soon as she heard the Lana Del Ray song playing, she just figured I was going to have Lana sing and we were going to have dinner."
Kanye popped the question with a lavish 15-carat rock, designed by Lorraine Schwartz, the celebrity jeweller favoured by the Kardashian family.
"The ring was four hours old from when I put it on her finger," said Kanye. "I had to pick it up in Los Angeles before. I was working on it for a while with four different jewellers."
Kanye confirmed that Kim will take his surname and that he will wear a wedding ring once the lovebirds tie the knot.
