Louis Tomlinson has hit back at claims from Rita Ora that The Voice is a better show than The X Factor.
Rita has joined the BBC One singing contest this series as a judge, but angered X Factor alumni and One Direction singer Louis with her comments that The Voice was more entertaining and held more talent.
An angry Louis tweeted: "Is bad mouthing The X Factor the only way The Voice knows how to promo their show ? #everyyear."
He added: "It's like Accrington Stanley trying to compete with Real Madrid ...."
Earlier in the week, Rita had said of The Voice compared to The X Factor: "We're definitely more entertaining as individuals. And the singers are better. And to answer bluntly, it's about music. It's a good show, a great formula, and there's no illusions.
"I don't know how X Factor works, I was only there as a guest judge for a day. But I watched The Voice a lot, I respected how it came across on TV and I love the freedom we get as coaches to do what we want."
