R+b star Mariah Carey wants to date a fellow celebrity - because only a man living in the media spotlight can understand the perils of fame.

The Hero hitmaker has remained largely single since her 1998 divorce from former Sony Music chairman Tommy Mottola, and insists any future boyfriend would have to be famous to be able to get along with her.

She says, "That's a big deal for me - feeling like somebody else can't fully understand me because they're not in show business."

"It shouldn't matter, but it does, because the energy it takes to be 'on' is a lot."
