Mariah Carey against Mary Carey

Mariah Carey has at last found out about her namesake porn star Mary Carey (real name Mary Cook) who has been very popular for a long time already. The singer is going to sue her for trademarking her similar-sounding stage name. Mariah is afraid that fans can get the two ladies confused.

Mary Carey: "I'm ready to battle Mariah over this because I've been Mary Carey for a long time," the porn star said."

Mariah Carey's lawyes say their client has almost no chances to win the case.
