What will take place on this Sunday's new episode of Keeping Up with the Kardashians?
That's what Khloe and Kendall want to know!
In the following sneak peek at the next new installment, the First Family of Reality TV is in a private jet (naturally) on their way to San Francisco because Kanye West has told them he has a birthday surprise plannd for Kim Kardashian.
What could it be?!? We all know the answer, of course, but watch the sisters speculate below:
The series itself has been in the news a lot this week, with talk of the Kardashians signing a $40 million deal to film beyond Season 11.
But will Bruce Jenner be included in future seasons? That answer remains unknown at this time.
