Kim, Khloe, Kourtney and Rob aren’t the only famous offspring of Kris Jenner. She has two daughters with her longtime hubby Bruce Jenner, and the girls (Kendall and Kylie) have plenty of fame of their own these days with the reality show and their respective modeling gigs. However, they’re both under the age of 18, so unlike their older siblings, can’t go out and do whatever they please, whenever! 17-year-old Kendall caused some major waves on Twitter yesterday, showing off a HUGE tattoo on her back. Something that probably wouldn’t be the best for her modeling career! Luckily, it turned out to be with a Sharpie marker! Phew! Kris and Bruce would have been PISSED! Check out the tat in the gallery.
