'X Factor' pair 'aggravating each other'

Tulisa Contostavlos and Nicole Scherzinger are "rubbing each other up the wrong way" on 'X Factor'.

The 'Young' singer - who famously fell out with Kelly Rowland on the last season of the show over Misha B's behaviour - is struggling to deal with how much attention new judge Nicole is getting and is "aggravating" her with the way she is in the auditions.
