The songs have now been removed from the production and replaced with original tunes and a representative for Webber's Really Useful Group said: "We are pleased that the producers of the Katdashians are cooperating in removing copyrighted material from their show. If you want to hear Memory live this summer, it looks like you'll have to go to Broadway, but it won't be performed by a 'Katdashian,' whatever that is."
Recently Lord Lloyd Webber launched a blistering rant against Nicole Scherzinger, 37, claiming she opted out of his musical Cats one week before Broadway rehearsals began, in order to return to The X Factor and fumed that he was furious with her.
He said: "A week before we were due to go into rehearsals with Cats, which luckily I'm not producing I have to say, she calls me and says she's decided to do X Factor, having agreed to it.
"She's crazy, but the American producers took a view of, 'Oh fine, we'll get someone else.' She's actually not that well known in America. She's better known here.
"I'm furious because I really believe she's the most fantastically brilliant girl and I went out on a limb to get her at the Palladium and now I look like an absolute t**t with them all.
"Nevermind, there will be another girl on Broadway and Nicole will not get her Tony Award."
Leona Lewis has since replaced Nicole in the role.
