Nope, the only thing I feel is happiness for my friend when they get any positive attention.
It is the confidence that is the attraction. Watch your friends are they trying to get attention or just being themselves? I found when I stopped worrying about what others thought, more people seemed to like me and want to be around me.
Yeah I have a friend like that as well - tall, blonde, big boobs, dumb brain, you know. But she always attracts the same kinda guys - douchebags. Do you want to attract douchebags? Nawwww
