Piers Morgan's team win last night's Celebrity Apprentice

Celebrity Apprentice contestant Piers Morgan was his team's knight in shining amour as he led them to victory in the US show.

The former tabloid editor dressed up in a chain-mail outfit to help sell tickets for Broadway shows in the latest challenge set by Donald Trump.

His turn as King Arthur from 'Spamalot' helped his men's team - including Brit boxing champ Lennox Lewis - raise more than $33,000 for charity to narrowly beat their women rivals by almost $2,000.

Talent show judge Piers raised more than $10,000 himself by persuading Sir Richard Branson to splash out on tickets for his Virgin Atlantic staff.

But he wasn't so happy during the task as he branded New Yorkers "heartless b******s" for repeatedly ignoring his sales pitch.
