Samantha Mumba and Westlife face the toughest judges in entertainment today - in the Disney Channel Kids Awards.
The votes of up to two million young viewers will determine who is really top of the pops.
It will also be a head to head against former Pop Idol rivals Will Young and Gareth Gates.
The Pop Idol winner and runner-up are set to go head to head as nominees for the title of best male in the Disney Channel Kids Awards.
Joining the pair in the list of nominees will be Kylie Minogue, who faces competition from girl band Atomic Kitten, and solo singers Sophie Ellis Bextor and Samantha Mumba for the title of best female.
After taking the singles charts by storm with her debut release Kiss Kiss, the Neighbours star Holly Valance is nominated for best newcomer.
But the real battle is for the title of best villain, with Pop Idol judge Simon Cowell lined up alongside the Queen of Mean Anne Robinson and Captain Hook, from Peter Pan.
The show’s presenters, Ant and Dec, face their old CD:UK co-host Cat Deeley for best TV star.
Gareth is due to perform at the awards at London’s Docklands Arena and is expected to be joined on stage by boy bands a1 and Blue, and Popstars runners-up Liberty X.
