Nicole Scherzinger thinks the US 'X Factor' is the Paula Abdul and Simon Cowell show.

The 32-year-old singer - who is on the judging panel alongside Paula, Simon and music producer L.A. Reid - is "fascinated" by the chemistry between the pair, who have been working together for over a decade in various ways, including as judges on 'American Idol'.

Speaking at the 95-106 Capital FM Summertime Ball at London's Wembley Stadium yesterday (12.06.11), Nicole told BANG Showbiz: "I'm not there to be in between them. I get The Front row ticket at the Paula and Simon show and I'm fascinated watching them, they've been working together for over 10 years.

"It's just an honour for me being part of the panel, being an artist."

Nicole - who replaced British singer Cheryl Cole as a judge on the panel - has completed her first round of auditions on the show, and has enjoyed the experience so far.

She added: "It's going great! I just had my first judging time in New Jersey. It was a lot of fun. The other judges are brilliant and inspiring to be around. We don't have private dressing rooms we like to keep it all out and open so we all share the same space."

She also had some words of advice to Kelly Rowland and Tulisa Contostavlos - who joined the panel on the UK version of 'The X Factor' following the departure of Cheryl and Dannii Minogue - telling them they just need to be themselves on the show.

Nicole added: "I would tell them just be yourself and have fun with it and speak from your heart. Try and be constructive if you can as well because these are these people's dreams."
