celebutante

I didn't know this was a word.
Then I read an article about Paris calling of her engagement to Paris.
She was described as a celebutante!

Defined by urban dictionary as: "A female of high society and wealth whose debut becomes publicly visible and famed; a debutante who achieves celebrity status."

Wikipedia defines it as: "A portmanteau of the terms celebrity and debutante. The term denotes a socialite who is 'famous for being famous'"
