Meow! It's getting "crazy" at Cats.

Former Pussycat Dolls singer Nicole Scherzinger abruptly backed out of playing in Broadway's "Cats" because she wasn't being given top billing, according to a new report.

Sir Andrew Lloyd Webber, the musical composer of the show, called her "crazy" for the last second withdrawal.

Nicole starred in the musical in London's West End and reportedly demanded her name be above the title for the Broadway show, as well as on the marquee, a source told the New York Post's Page Six gossip section.

Producers of the show weren't as keen on that idea and gave her the hard pass. Nicole then decided to pull out of the show, despite the fact that rehearsals were supposed to start next week. Nicole will instead head back the United Kingdom to judge the talent show, "The X Factor."

It's been announced that fellow "X Factor" star Leona Lewis has replaced Nicole and she's begun rehearsals.

Andrew opened up about the incident to the Economist Radio, saying, "I mean, [Nicole] is crazy. But the American producers just took a view — 'well, fine, we'll get somebody else,' because she's actually not very well-known in America."

Perhaps he's right. "Don't Cha," by far the Pussycat Doll's most popular song, came out 11 years ago, which is certainly when Nicole's popularity peaked in the United States -- to give you an idea of how long ago that was, President Bush was only beginning his second term at that point. Her star power has never been as big as it was then, at least in the U.S.

Andrew said, "I'm furious because I really believe she's the most fantastically talented girl, and I went out on a limb to get her for the London Palladium here, and it makes me look like an absolute [bleep] with them all.

"But never mind, there'll be another girl on Broadway, and Nicole will not get her Tony Award," he said.

Over the weekend, Nicole attended a party in Southampton, New York but reporters in attendance were banned from asking questions about her departure from the Broadway show.
