Nicole, 37, was in talks to reprise her role as Grizabella, whom she played in a 2014 production on London's West End, in a new version scheduled to open in the New York theatre district next month (Jul16).

However the veteran theatre impresario, who recommended her to the show's producers, was left furious after she announced last month (May16) that she was dropping out to join the judging panel of U.K. TV talent contest The X Factor.

Ironically, her role in the musical has been taken by The X Factor's 2006 winner Leona Lewis.

Andrew, who composed the musical, now believes her decision to pull out may mean she is blackballed by Broadway producers who were sceptical about her casting.

"I had to fight to get her into the Broadway production," he tells British newspaper The Sun. "The American producers had not seen what she could do. She took them to the eleventh hour and everything was agreed with her manager, who has since resigned over this. He’s not representing her anymore."

He adds, "I just wanted her to be able to show the Broadway community how good she is. I hope she will get another opportunity, but the chances are not great, because it’s a very small world there."

Upon revealing she was dropping out of the show, which begins previews at Manhattan's Neil Simon Theatre on 14 July (16), Nicole told London's Evening Standard newspaper, "I had every intention of doing Cats on Broadway but the contract was never finalised."

She added, "I am incredibly blessed to be given so many amazing opportunities, including Cats, but unfortunately we weren’t able to make it work this time around... I adore and respect Andrew, I’m so grateful for our friendship and can’t wait for the opportunity to create more magic together."

However, Andrew was less than complimentary about the former Pussycat Dolls singer after she quit.

"I it makes me look like an absolute twot (sic) with them all (Cats' producers)," he told The Economist Radio podcast. "But never mind, there'll be another girl on Broadway and Nicole will not get her Tony Award."

After previews, Cats officially opens on Broadway on 31 July (16).
