I think she should do it. She doesn't really have anything going on right now other than her kid and some other business ventures and I think she would be a good judge. Cheryl Cole is back so they would be a good pair of girls for this season I think.
honestly she wont benefit much from the x facotr uk. Simon should have hired Fergie on the u-s x factor from day one. he was silly to ever try with all the other pop girls he brought on board. Fergie should do The Voice US. she would be fantastic on it to be honest. The X factor UK needs to keep Nicole as the fourth judge. not only will it bring views because ppl will keep checking in to see who looks best every week between Nicole and Cheryl but Nicole's only credible market is the UK at this point.
and anyway even if she hasn't released anything since 2012 , it would be a step back doing that kind of shows.Hopefully she will release a new single/album for the end of the year
