Louis Walsh has said he prefers working with Sharon Osbourne on The X Factor because she is "more fun and reliable" than Tulisa.
Sharon is back on this year's judging panel and has taken over Tulisa's vacant seat.
Fellow judge Louis told the Daily Mirror: "Working with Sharon again is fun. Love her, it's fun going to work, it's not like working. We all get on incredibly well this year."
When asked how different Sharon was to Tulisa, he added: "She's more fun. And reliable. Oops!"
Louis admitted he thought Nicole Scherzinger's girls could be tough to beat this year, but thought there might be a contestant in his boys category who could do it.
He said: "I've got a really good category. There's one person in my category that I think could win it, yeah. Not telling you."
