High Flying Romance! Kylie Jenner & Boyfriend Tyga Take Their Relationship To The Next Level

They are already in another exotic locale. But before Kylie Jenner and Tyga joined the rest of the Kardashian clan in St Barths they took their relationship to the next level in Mexico with some treetop zip-lining on Thursday.

While Kylie, 18, has worked to separate herself from the looming shadow of her big sisters, the scene was reminiscent of Kim Kardashian and Kanye West performing similar high wire work just over a year ago.
