Kylie Jenner loves stealing the spotlight when she can and Saturday night at Nobu was no exception! The cosmetics mogul - who recently celebrated her 23rd birthday - played third wheel by joining sister Kendall on her date night with NBA star Devin Booker of the Phoenix Suns. Kylie totally stole the show by rocking an impossibly short mini-dress which could barely contain her assets! Kendall and Devin were first linked together back in April but rumors of a romance became far more prominent when their flirty Instagram messages went viral.
