These are the kind of parents that will do just about anything to gain fame, money or prestige through the beauty and cuteness of their children. A good example of these type of parents can be found in reality shows like "Toddlers and Tiaras" or "Dance Moms".
Becky: Did you see that dance routine that Ava performed on "Toddlers and Tiaras" last week?
Grace: *sighs* Yes.
Becky: What's wrong with it?
Grace: There's nothing wrong with the routine, or with Ava - for that matter. It's her parents.
Becky: There's something wrong with her parents?
Grace: Yeah, *scoffs* they're stage parents, duh!
