When the new season of "Keeping Up With the Kardashians" kicks off this weekend, fans will get to witness the courtship between [article id="1664525"]Kim and her basketballer fiancé Kris Humphries[/article]. Sisters Khloé and Kourtney spoke to MTV News about Kim's very surprising impending nuptials, admitting that they didn't see it coming.

"Mine was insanity in the best way ever," Khloé said of her quickie [article id="1622109"]engagement to Lamar Odom[/article]. "But [with] Kim's, we were totally surprised. I mean, because I had been working so much, and Kris lives in New Jersey, I've only met him not even a handful of times.

"We were at a family dinner and she walks in, and she's like, 'I'm engaged,' but we didn't even know if it was a joke," Khloe added.

Kourtney was also caught off-guard. "We were like, 'Is this for real? What's going on?' " she said. "We were definitely all surprised. I had even just been on a vacation with them and was still really surprised."

As with most major moments in the Kardashians' lives, the romance was all taped, so maybe when we see the whole story, their decision to get married won't seem so sudden.

"But that's the cool thing about this whole season: You do get to see Kim [and Kris] kind of from the beginning of the relationship to the engagement," Khloé said. "Obviously, no one knew in between what was going to happen, so it's cool that they have it documented for their future."
