A few of my actual friends are actors on popular TV shows.
I get regular (almost daily) Facebook friend requests from (usually) attractive girls I have never met. When I look at the “mutual friends” thing that shows up, it’s always one or more of the actors.
Turns out that if some groupie manages to befriend one of them on FB, they go through their whole friend list trying to add everyone, on the basis that a large number of them are celebrities.
Can’t imagine it works very often though, since most of them have personal accounts and “work” accounts.
I’d be lying if I said I didn’t accept the request of the occasional, very attractive one. Just for a look 🙂
