It may have happened back in October, but we found out that it almost didn't happen at all on Keeping Up with the Kardashians Season 9 Episode 5.
We're speaking, of course, about Kanye's surprise engagement to Kim. EEK!
On Sunday's installment of the E! reality show, we watched as Kim nearly walked in on Kourtney talking about the birthday plans, while we then saw the rest of the family take a private plane to San Francisco for the big event.
Their reactions were priceless, but nothing topped that of Kim herself.
There was dancing, there was drinking, there was merriment all around after Kanye got down on one knee and Kim said yes.
Sadly, Scott could not join in the fun because his mother was very sick.
