Pack your bags Kardashians because it's time to witness one magical proposal!

In a sneak peek at Sunday's Keeping Up With the Kardashians engagement event, the family heads to San Francisco for what's being called a birthday surprise for Kim Kardashian.

But with Khloé Kardashian onboard, the investigation as to what's really going on continues.

"The only information, which I got, was that it was black tie," Khloé said. "I wonder what this is going to be like," Kendall Jenner added.

Unfortunately, Kris Jenner is staying super quite on Kanye West's big plans.

"Actually he said to me he has big surprises for us," the momager said. "But I don't know. I'm in the dark." Hmmm, you sure about that Kris?

Kourtney Kardashian has high hopes for the birthday celebration.

"What if it's a surprise wedding?" she asks.

"Shut up!" Khloe proclaims. Hey, at least Kourt is thinking in the right direction.

"We cannot project what is going to happen and I think we need to relax and enjoy the moment," Kris says as she tries to put the rumors to rest. We'll try our best, Kris!
