Whatever is going on here, the two Keeping Up With the Kardashians sisters are apparently displaying that special bond that Kylie previously expressed by sucking Kendall's tongue. Another snap reveals the two dancing, and having a good time together.

In a post on Kendall's own page, the 20-year-old  model confirms that despite how in sync she and Kylie are, the moves were "unrehearsed."

Despite the love, the two do fight like sisters. A clip from KUWTK last year shows what happened at the ESPY Awards when Kylie wouldn't let her sister borrow a dress.

"You're just literally the biggest f**king bitch I've ever met," Kendall said during the heated exchange.
