They didn't state clearly why she was kicked out, but did say something that she didn't perform a number of her Miss Universe duties, "might be married to her longtime boyfriend -- a violation of pageant rules -- and could be pregnant."
She said she wasn't kicked out and she gave it up on her own, but still considers herself "miss universe"
