The blonde beauty even added a festive martini glass emoji for good measure. Fellow catwalk queen Karlie Kloss also posted a tribute to the Keeping Up with the Kardashians star, and 'grammed a cute picture of them hanging out at a basketball game while trying out the puppy Snapchat filter. "Happiest of days to this bday queen @kendalljenner love ya lady!" she wrote alongside the fun image.
