Scherzinger will prepare contestants for success

Nicole Scherzinger will teach 'X Factor' contestants how to make it on the ''worldwide stage''.

The former Pussycat Doll joined the panel of the UK show this year - alongside Gary Barlow, Tulisa Contostavlos and Louis Walsh - and co-executive producer Mark Sidaway says she was approached for the role because of her international appeal and experience.

He told the Hollywood Reporter: ''Nicole is an international artist, so she knows what it takes to make it on the worldwide stage.

''She has worked hard to get where she is, and she'll bring that experience to the show and she'll be able to use it with her contestants.''

Mark also revealed Simon Cowell is still hugely involved, despite quitting the show to focus on the US version.

He explained: ''He is involved across our plans for the show and is as passionate about this as he is about the US version.

''Every year we bring fresh ideas to the series, as even though we are the country's number one entertainment show we don't rest on our laurels We want to keep it surprising and fresh for everyone who watches the show.''
