Kylie's actual birthday is August 10, and ET chatted with her pal
, Jordyn Woods, ahead of all the festivities, and got an inside look into their sweet friendship
. "You know, together her and I -- and all of our friends -- we just always build each other up no matter who it is," the model shared. "Whoever I'm around, I just want to see them do their best. So whenever we're all together, we just always motivate each other, and just tell each other how beautiful they are every day."
