Piers Morgan: 'Carey right to be a diva'

Piers Morgan has said that he can understand why Mariah Carey is such a perfectionist.

The America's Got Talent judge said that Carey kept the cast and crew working all night to make sure she was satisfied with her upcoming appearance on the show.

He told the Daily Mail: "Mariah's the wife of our new host, Nick Cannon, and it was not difficult to see why she is the most successful solo female recording artist in history.

"She's such a perfectionist that we were all in the studio until nearly midnight as she planned her three-minute appearance, right down to the detail of lighting, sound and camera angles.

"And work with producers in the editing suite apparently continued to 6am until she was absolutely happy."

He added: "Mariah has a reputation as a bit of a diva. But like most other divas in musical history - from Piaf to Whitney Houston, Diana Ross to Madonna - that's primarily because she'll do whatever it takes, however long it takes, to get things as good as they can be. Which is why she has sold 200 million albums.

"'I don't think anyone knows as much about what's right for me as I do,' she once said. A pretty good maxim to have in showbusiness."
