In case you forgot what a big year Kim Kardashian had in 2013, a photo she posted on New Year's Eve, of her baby North holding her engagement ring, serves as a reminder.

"It was an amazing year!!!" Kardashian wrote in the caption in the Instagram photo posted Wednesday.

Not only did Kardashian welcome her first child with Kanye West in June, but the couple got engaged in October and even starred together in the steamy video for West's "Bound 2."

In a YouTube video posted Dec. 30 under the name Kim West, Kardashian looks back on their whirlwind romance.

"Happy endings do come true!" the reality star captioned the video titled "Kimye Love," a mash up of pictures, interview clips and paparazzi footage of their relationship, set to Rihanna's "Stay" and Keri Hilson's "Knock You Down."

"I don't know why it took us so long to get together," Kardashian, 33, says in one interview clip after stating that she met West almost a decade ago. "I think we've always had an attraction for each other."

"I've never loved any girl, other than my mother, as much as I love my girlfriend," West, 36, says in another interview clip.

That is, of course, until their baby North West came along.

In the video, Kardashian includes a clip from her show, "Keeping Up With the Kardashians," in which she recalls what West had to say before the birth of their child: "'There's nothing more that I love in this world than you and me. So imagine a combination of the two."
