Here's the cycle: the talk show host (or columnist or Barbara Walters type) exposes somebody to the public. Which makes them famous. So the talk show host (or gossip columnist or Barbara Walters type) gets famous, too. Which makes the next somebody they expose to the public a ""personality."" And famous.
