We decided to throw him our own little online party by rounding up 15 of his hottest selfies! One thing we learned while rounding up his photos is that no matter where he is, he loves taking a selfie! From a rooftop in New York to getting ready for an event, Kendall always shares his whereabouts with his fans. And we can't complain because we love his stylish baseball caps and outfits!
