Simon Cowell has opened up about spat between Cheryl Fernandez-Versini and Louis Walsh saying that they both are like Tom and Jerry.
The 'X-Factor' boss asserted that there was always going to be a clash and he wish they would fight more on the singing reality show instead of arguing on Twitter, the Daily Star reported.
The recently fired judge Walsh had hit out at his former colleague Versini, calling her "lazy" and "irrelevant", and suggesting Mel B or Nicole Scherzinger should be back on the panel instead of her.
Versini reverted back to him saying that Walsh must be "obsessed" with Scherzinger or Mel B.
