Are shawn johnson and nastia liukin good freinds?

Question

hey guys all gymnastics fan saw what happend tonight in the all around and it truly was amazing having worlds number 1 and 2 both be american and on the podium. anyway i know shawn and nastia are obviously freinds as both of them are on the team together. but are they as close as they seem to be? i mean both seemed to be very happy for each other and i dont blame them not only are both of them gorgeous but both are super athletes. but ya are they really really good freinds.
