Kanye released his new track "Theraflu," revealing the lyrics "and I'll admit, I fell in love with Kim 'round the same time she had fell in love wit' him. Well, that's cool, baby girl, do ya thing," in reference to Kim's relationship with Kris Humphries.
The next day, Kim responded during a Today show interview , saying, "Kanye and I have been friends for years, and you never know what the future holds or where my life will take me. I like the song."
Khloé Kardashian coyly addressed rumors that her sister Kim was dating Kanye by saying, "We've known Kanye forever. He's been a great family friend. . . . I think they're cute together. . . . They're compatible."
The duo made their public debut as a couple  on the streets of NYC after weeks of rumors that they were dating.
Kim and Kanye showed their first PDA on the set of her Vogue Italia photo shoot in LA. The kiss came just a few days after Kanye attended Kim's sister Kourney's baby shower with the whole Kardashian family.

Kim and Kanye made the rounds during Paris Fashion Week, and Kim broke from the festivities to gush about Kanye's great taste. She told E! news that she wasn't worried about what Kanye would give her  for her birthday, saying, "See, the thing is, my boyfriend, he has such good taste that I don't need to [tell him]."
They showed lots of love  just days after Kanye announced Kim's pregnancy during a concert in Atlantic City, NJ. Kim later took to her website to confirm the news, writing, "It's true!! Kanye and I are expecting a baby. We feel so blessed and lucky and wish that in addition to both of our families, his mom and my dad could be here to celebrate this special time with us. Looking forward to great new beginnings in 2013 and to starting a family. Happy New Year!!!"
Kanye and Kim celebrated their baby news by ringing in the New Year in Las Vegas. The next week, it was reported that they purchased an $11 Bel Air mansion  in LA together.
Kim posed for DuJour magazine's Spring 2013 issue  and revealed how dating Kanye changed her: "My boyfriend has taught me a lot about privacy. I'm ready to be a little less open about some things, like my relationships. I'm realizing everyone doesn't need to know everything. I'm shifting my priorities."
Kim and Kanye shared a rare glimpse at their relationship in a steamy cover shot for L'Officiel Hommes.
Kim showed off her growing bump at the premiere of Temptation in Atlanta, where she opened up about the pregnancy after a miscarriage scare earlier in the month. Kim said, "Being pregnant is not as easy as my sister made it look or my mom made it look. It's a little more painful. I've gotten sick a couple times."
She sat down on The Tonight Show to talk baby names with Jay Leno . At the time, she and Kanye hadn't revealed if they were expecting a boy or a girl, but she and Jay threw around ideas with Kim, sharing that she and Kanye "have a list, and some of them are K names and some of them aren't." Jay brought up the rumor that they were thinking of North West, and Kim quickly denied the idea, going on to say, "One of the names I do like — I like Easton. Easton West. I think that's cute."
Kim and Kanye stepped out in NYC as news broke that Kim and Kris Humphries had reached a divorce settlement. Earlier, she had expressed concern about still being legally married  to Kris when giving birth to her child with Kanye: "I firmly believe that an immediate dissolution of our marriage will help create a new, full life for me. I do not want to be married . . . when I have my baby."
Kanye and Kim reportedly went house hunting as they prepped for the arrival of their first child. The couple remained quiet on the gender of their baby, though it was all but confirmed they'd be having a girl when pink baby-shower invitations featuring a ballerina were sent out.
Kanye had pregnant Kim as his date at the Met Gala. Inside the event, he took the stage to perform and defended Kim  against haters, saying that she shouldn't worry what anyone says and that she's awesome.
Kim was surrounded by friends and family, including Kanye, at her Beverly Hills baby shower. The couple asked for donations to Chicago's Lurie Children's Hospital  instead of gifts for their baby girl. They had even more to celebrate, since Kim's divorce from Kris Humphries was finalized .
A week later, Kanye's rep responded to rumors  that he cheated on Kim with model Leyla Ghobadi, saying, "This most recent attack on Kanye West  and his family is totally without merit. It's a blatant attempt by a misguided individual who is clearly seeking publicity and another in a series of malicious stories drummed up by noncredible 'news' sources. This is a sad attempt to hurt two people trying to live their lives."
Kim and Kanye welcomed their daughter! The baby girl was born a few weeks ahead of her anticipated due date but was reportedly healthy. It wasn't until almost a full week after her birth, when her birth certificate became public record, that the little girl's name was revealed as North "Nori" West.
Kanye told W Magazine  the reason that he appeared on Keeping Up With the Kardashians: "Oh, that's just all for love. It's simply that. At a certain point, or always, love is more important than any branding or any set of cool people or attempting to impress anyone. Because true love is just the way you feel. Thoughts and feelings can disagree sometimes."
