They’re the famous faces you know, but can’t remember why you know them. You can’t stop reading about their salacious lives on sites like Perez Hilton and TMZ. You find yourself in late-night YouTube spirals with absolutely no idea how you got there. You, friend, are in a D-list descent.

What exactly is a D-lister? It’s a very tough thing to define precisely; it has nothing to do with a celebrity’s actual level of professional or financial success—in fact, many of the folks on our list (as you’ll see) are doing quite well for themselves. Rather, it’s a more nebulous, all-in-good-fun label attached to a star who at one time was at Beyoncé-level (or close to it) heights of fame and now—well, not so much.
