Mariah and her costume here. You're already a bitch and a DIVA you really didn't need to advertise it. This is how she showed up with her family (and also new boyfriend) to her Halloween party that she hosted. When Mr. Cannon found out he was invited I am sure the conversation went something like......
Maraih: You can come Nick but whatever slut your dating this week is just not invited. You also need to be extremely respectful because my new Billionaire boyfriend will be there.
Nick: OK Mariah, not a problem.
On a side note; the kids looked adorable, than again all the kids do on Halloween.
