Khloe Kardashian is one smart lady!
In a sneak preview for Sunday's all new Keeping up with the Kardashians, the famous sister gets a phone call from Kris Jenner that immediately raises some suspicions.
"Mom called me and said Kanye is going to send a private plane and he wants us all in San Francisco," Khloé explains to Kourtney Kardashian. "We can't say a word."
But instead of speculating the reasons behind this top-secret trip, Kourt is more excited about the required dress code. "Black tie is fun!" she says.
