Kylie Jenner and Travis Scott showed some MAJOR mom and dad PDA while they were on vacation...however we've learned that isn't stopping Kylie from being CAUTIOUS about marrying her boyfriend and baby daddy…and I have to tell you guys WHY. On a positive note...it looks like we might get a couples vacay sometime here soon with two of your fav celeb couples because Kylie JUST invited Justin and Hailey Bieber on her Travis's next vacation.
