I'm with GAMerican, but...
Having worked all my life in sports, I've met some sports celebrities, and one or two of them became very good friends. The difference here may be that in sports, celebrity implies achievement, rather than, say, inherited good looks, which, combined with a willingness to take of one's shirt = fame.
I'm deeply fortunate in that one friend turned into a celebrity, and one celebrity turned into a friend. Josh Thompson and Thomas Wassberg, if there are any sufficiently ancient x-c skiers lurking around here. And I'll be it's the first time either of them has been mentioned on a gay site!
