Nick joked this week: “She is like Joey with a good weave.”
Speaking to The Sun newspaper, he continued: "She’s so funny and doesn’t even know when she’s being funny. Her geography’s unbelievable. Her naivety’s quite charming.
"People will fall in love with her over it.
And show boss Simon Cowell seems to agree, saying recently: "She's really funny and a bit of a ditz. I never saw The Voice but I think she's very relaxed on our show."
Rita was left red faced during auditions last month after a number of ridiculous remarks which included having to ask if Cheryl's hometown of Newcastle upon Tyne was “part of the British Isles”.
However Rita has brushed off what her critics may say in a new interview with Glamour magazine.
Rita, who whips a boob out in the photoshoot for the publication, says: “I’ve worked hard to be involved with everything you see my name associated with.
"It doesn’t happen overnight, and I feel I have as much right to be on that panel as everyone.”
