Louis Walsh has described his time in Las Vegas for judges' houses as "fantastic".

The Irish music mogul decided to jet out to the US this year, instead of making the hop to some castle in Ireland like in previous years.

And it sounds like the journey was worth it!

He said: "It's fantastic, Las Vegas is the most exciting city in the world, and everybody wants to come here, including Prince Harry!

"I always like doing it in Ireland but I'm glad I cam here because it's very warm. I don't care where they need me - it's about finding three acts and that's my job."

Louis decided to bring along pal and former X Factor judge Sharon Osbourne to help him decide on which acts to take through to the finals, and it sounds like the pair were loving being on the show together again.

"She is the same as always, full of life and energy," Louis said. "Honestly we just talk and talk and talk . We are old friends. I was lucky to have her as my guest judge."

He added: "I miss her a lot on the show and I would her to come back next year."

Other celebrity helpers for this year's judges' houses have included Cheryl Cole, Ne-Yo and Tinie Tempah.

The X Factor 2012 continues Saturday and Sunday nights on ITV1.
