Jennifer Love
Paulina Rubio
Hilary hmm I like her but idk.
I do think Kelly, Demi and Cheryl along with Simon would be great and would be different.
Demi: appeals to younger people/teenagers.
Simon: hmmm
Cheryl: the new face(kinda), returning to the show would bring lots of publicity. The British queen of beauty.
Kelly: Would be eye candy for man and would bring urban viewers.
Plus Kelly and Cheryl are always so on point when it comes to fashion. Imagine the fashion wars
