Kreepy or Kool? On the latest episode of "Keeping Up With the Kardashians," fans learned a bit more about Kim Kardashian and her step-brother Brandon Jenner: the two locked lips "back in the day." During a vacation in Thailand Brody Jenner was being teased about "having a crush on Kim" when he dropped a bombshell about his brother Brandon and stepsister Kim.

In last week's episode, Brody accidentally walked in on the mother-of-one doing a photo shoot wearing nothing but a wet white t-shirt. After running out of the room, Brody jokingly told Brandon and his wife Leah Jenner, that he might have gotten a little excited after seeing Kim practically naked.

In Sunday's episode, Kris Jenner teased Brody that he had a crush on his stepsister.

"I feel like Brody is crushing on Kim," Jenner joked.

Brody denied he had a crush on Kim and told everyone that Brandon kissed the brunette reality star when they were younger.

"That was [Brandon] and Kim, you are forgetting that they kissed back in the day," Brody responded.

Jenner couldn't believe what she heard and Brandon ducked his head in embarrassment and mumbled "It's not true."

Everyone knows Kim loves taking sexy selfies and on the episode Kris revealed that her daughter weas working on a selfie book... yes, a selfie book. Apparently, Kim needed 1,200 selfies for the book and she used different backdrops in Thailand for settings.

In a bonus clip of the episode, North West's mama is seen talking on the phone to hubby Kanye West and reveals that she brought along six cameras (plus her iPhone camera) so she could take selfies all day.

"It's ridiculous. We look like crazy tourists," she told West.

After ending her call with the rapper, Kim stopped by a sitting room in their resort to visit her mom and take another photo.
