Barry Humphries is preparing to open It's All About Me in New York, featuring his drag-queen alter-ego Dame Edna.
But the star is fuming after discovering American singer Feinstein has chosen a similar name for his upcoming production - All About Me.
Both shows will open in March (09), with Feinstein's act opening a few days after Humphries'.
The Australian comedian says, "It's All About Me is my title. While I was saddened to hear that Mr Feinstein did not heed my sage advice to change the title of his show, I'm overjoyed to hear that he at least took my suggestion to open his show after mine. I'm sure Mrs Feinstein is very proud of her son."
But Feinstein has hit back at Humphries, insisting he was "very surprised to learn of the similarity of (the) titles," adding: "Titles are not copyrightable. I wish Ms. Edna well. I've heard of her."
