Nigel Lythgoe on getting his star on the Hollywood Walk of Fame, the future of reality TV, and his nickname 'Nasty Nigel'

On Unscripted this week, Nina is joined by television and dance impresario Nigel Lythgoe.

Nigel talks to Nina about getting his star on the Hollywood Walk of Fame, and where he thinks modern reality TV is going wrong - and what needs to change.

The talent show judge reminisces over his nickname 'Nasty Nigel' and how 20 years on from Popstars, he's still hearing it.

And the pair talk what to do with old television that's dated, even offensive, in the 21st century.
