But how, exactly, did America's most eligible bachelorette get taken off the market? Well, thanks for asking!
Kris Humphries managed to do what Reggie Bush, Gabriel Aubry, Miles Austin, Cristiano Ronaldo and (flashback alert) Ray J couldn't quite manage—secure Kim's hand in marriage—after both a stealth and rapid courtship. So let's take a look back together at how he managed such a feat:
2000: At just 19 years old, a pre-fame Kim Kardashian enters into an ill-fated marriage to music producer Damon Thomas.
2003: The couple divorces. It takes several years, but documents pertaining to the split are eventually unearthed and reveal allegations of abuse leveled against Thomas.
2007: Rumors as to the existence of a sex tape between Kim and then-boyfriend Ray J (that'd be Brandy's little bro) emerge, and are eventually proven true. Kim denied involvement in the film's release, and sued Vivid Entertainment for ownership rights, though eventually dropped the suit after reaching a settlement.
October 2007: The Kardashians become a household name, as Keeping Up With the Kardashians debuts on E! (You're welcome, world.)
2007: Kim begins a three-year, on-off relationship with Reggie Bush that is featured heavily on both her reality show and in the tabloids, and is plagued by rumors of engagements, which ultimately were unfounded.
July 2009: Kim and Reggie break up (take one).
August 2009: They're baaack!
March 2010: Kim and Reggie break up. For good.
April 2010: Rebound, thy name is Cristiano Ronaldo! Kim is spotted getting quite cozy with the international soccer phenom in Madrid; sources said the duo, despite living on different continents, were keeping in "daily contact."
June 2010: Eh, love is fleeting. Kim is spotted with Dallas Cowboys receiver Miles Austin after the duo meet and exchange numbers at an L.A. restaurant.
August 2010: After they're caught sharing a steamy Fourth of July kiss, Kim confirms the budding romance, announcing that she's "definitely dating" the footballer.
December 2010: Amid rumors that Halle did not approve (and that custody of his child could be at risk) Gabriel and Kim abruptly cut ties.
December 2010: Kim first steps out with Kris, days after splitting from Gabriel.
Early January 2011: Just a few weeks after going public with Humphries, Kim meets the parents, flying out to a Minnesota Timberwolves game to cheer on her beau alongside Kris' sister, Kaela, and his parents. They later shared dinner together, and Humphries' rep said at the time, "Yes, they met and it was a wonderful meeting." First impressions are everything!
January 2011: Babies on the brain? Kim tweets a photo of Kris as a child, with the caption, "I want my son to look like this!"
Feb. 5, 2011: Kim helps Kris celebrate his 26th birthday with a surprise birthday dinner in NYC with his parents.
March 2011: Kim denies rumors that she and Kris are already engaged.
March 2011: Call it sisterly instinct. Khloé Kardashian Odom, who knows from quick courtships, tells E! News that Kim "thinks she is" going to marry Humphries, calling her sis a "hopeless romantic."
April 2011: Kim tells E! News that moving to New York (Kris plays for the New Jersey Nets, remember) is the "obvious" next step, but plays coy about any permanent plans. "We're doing good!" she said of her relationship. "I am very happy where I'm at...But as of right now, no marriage, nothing like that. We're happy."
Early May 2011: Just a week before Kris proposes (and two weeks before the world learns of the engagement), Kim again addresses rumors of an impending engagement. "I'm like, 'Seriously?'" she told E! News. "We laugh so hard. I mean, I guess it's flattering that they want us to get married instead of break up, so I don't know."
May 18, 2011: Humphries gets down on bended knee and pops the question to his girlfriend of roughly six months, asking for her hand in marriage with rose petals spelling out the question, "Will you marry me?" She of course accepts. The 20.5-carat diamond probably helped.
May 19, 2011: The day after the proposal, the couple (careful not to reveal their news) heads out on a date night in Hollywood, walking hand-in-hand in front of the paparazzi.
May 25, 2011: The couple announce their engagement to the world. "OMGGGGGG!!!!!!!" Kim blogged. "It's true! I couldn't be happier! Thank you guys for all the sweet messages!!! I finally found my missing puzzle piece, I'm complete."
No wedding date has yet been set, and the couple are currently en route to a vacation in Monaco.
