Olly Murs and Caroline Flack miss the "fun" of 'The Xtra Factor'.
Rochelle Humes and Melvin Odoom
The presenting duo now host the main 'X Factor' show and current spin-off hosts Rochelle Humes and Melvin Odoom feel lucky they don't have to be as serious on the ITV2 programme.
Melvin said: "If anything, Olly and Caroline remind us how lucky we are, because I think on the main show it's all about the talent.
"With us, we're there to have fun and do silly things.
"I think they probably miss the fun they had on 'The Xtra Factor'."
Rochelle added: "They've had to be a bit more serious, haven't they?"
The pair also admitted they are both so critical of themselves, they refused to watch their 'Xtra Factor' debut with anyone else.
Melvin said: "When the first show went out. I had to watch it by myself."
Rochelle added: "All of our friends and family wanted to come to our houses and we were like, 'No!' I didn't even watch it with my husband."
Rochelle is married to former JLS singer Marvin Humes - with whom she has two-year-old daughter Alaia-Mai - and she admitted she frequently gets his name muddled up with her co-host's.
She told heat magazine: "If I'm nagging [Melvin], I#l call him Marvin and if I'm nagging MArvin, I'll call him Melvin."
And the DJ also frequently gets called Marvin when he's spotted in the street.
He said: "I get called Marvin in the street, I don't mind that. I'm like, 'JLS was a good time for me.' "
