Nicole Scherzinger never thought she was ''good enough''.

The 'Poison' hitmaker recently revealed she had battled bulimia during her time in the Pussycat Dolls but she has now learned to love herself and gained confidence.

Miley Cyrus turned down a judging role on 'The X Factor' USA because she didn't want to be a ''dream crusher''.

The 19-year-old singer was approached by Simon Cowell's team about joining the talent show as a panellist, but she rejected the role because she doesn't believe she would have been able to criticise the contestants' singing even if they sounded like ''nails on a chalkboard''.

Nicole Scherzinger is ''very qualified'' to be a talent show judge, legendary choreographer Travis Payne has claimed.

Travis - who is best known for inventing some of Michael Jackson's signature moves - immediately saw star potential in the former Pussycat Dolls singer while judging US programme 'Popstars' in 2001 and thinks she has all right qualities to mentor other pop hopefuls on British series 'The X Factor'.

Gary Barlow is reportedly planning to quit 'The X Factor' after the current series.

The 'Take That' singer - who claimed he was ''embarrassed'' to be a judge last weekend after his act Carolynne Poole was booted off the show in favour of controversial performer Rylan Clarke - is said to be preparing to reunite with his bandmates for a new album and tour so he won't have time to work on next year's series of the show.

Paula Abdul is to be a guest judge on 'Dancing with the Stars: All Stars'.

The 50-year-old singer will join the panel of experts on next Monday's episode (15.10.12) to assess the star-studded line-up of the ABC ballroom dancing competition.

Nicole Scherzinger refused to share the spotlight with the rest of the Pussycat Dolls according to her ex-bandmate.

Former Pussycat Doll Kaya Jones has hit back at the 'Don't Hold Your Breathe' singer for claiming in her upcoming VH1 'Behind the Music' special that she did 95% of the singing herself and the rest of the group did not record any vocals for their albums.
