Katdashians! Break the Musical! combines the award-winning Cats musical with the life of arguably the most famous family in the world.
The musical mash up includes Kim, Kourtney, Khloe and Rob Katdashian as well as Caitlyn Jenner who'll be played by a transgender actor.
The idea, however, has not gone down well with Cats co-creator Andrew Lloyd-Webber - he's accused the team behind the Katdashians! of stealing his ideas and songs.
The musical legend has reportedly fired off a legal letter to the team behind the new musical, claiming that ‘continued willful infringement on our client’s rights’ would result in a claim for damages.
