MARIAH CAREY is threatening legal action against MARY CAREY, because the adult entertainer is planning to trademark her similar-sounding stage name.
The WE BELONG TOGETHER singer is worried fans might confuse the two performers if Mary Carey's application to trademark her name for audio and video recordings is successful.
However, the porn star - real name MARY COOK - insists she's not intimidated by the Grammy Award winner, saying, "It's kind of funny because I'm a porn star and I've been being myself for a long time. I think she's being silly." Cook's lawyer DAVID BEITCHMAN insists the singer stands little chance of winning a court battle over the names.
He says, "My first thought was, does Mariah Carey realise what her lawyer is comparing her to and are they seriously concerned? Do they seriously think the fans are going to be confused?"
