Aiken to guest judge on 'Top Model'

Clay Aiken will reportedly appear as a guest judge on the next series of America's Next Top Model.

The American Idol star will join host Tyra Banks and fellow judges J Alexander, Nigel Barker and Paulina Porizkova for an episode of the US reality show later this month, reports WENN.

Aiken will participate in an acting challenge with the model hopefuls, while R&B singer Ciara will also make an appearance in the same show.

The musician finished runner-up to Ruben Studdard in the 2003 series of Idol and went on to sell more than 1 million copies of his debut album Measure Of A Man.
