The family did a photoshoot for the 10th anniversary of Keeping Up With The Kardashians, and one photo in particular made fans a little grossed out.
Kylie is licking her sister's boob. Lol.
It comes after the same two sisters did a similarly as close photoshoot for their makeup collaboration.
"These intimate shots are super weird because you're sisters..." one fan commented.
"This makes me uncomfortable lol," said another.
And let's not forget that brother Rob Kardashian just admitted that he dated a girl who won a 'Kim Kardashian lookalike contest'.
Yep, this is real life.
