Robbie Williams is to appear on a one-off TV Christmas variety show organised by presenters Ant and Dec.

The two British presenters, pals of the pop singer, will host the entertainment show that will be recorded in front of a live studio audience.

It will include sketches, performances as well as guests and interviews and Robbie has reportedly agreed to sing live on the show as well as team up with the lads for a number of sketches.

A source told British newspaper The Sun: “Ant and Dec have been given the green light to make a Christmas special which will be ITV1’s big family entertainment show this Christmas.

“They came up with the concept and pitched it to ITV. Their own company, Gallowgate, will make it. Robbie is really excited to be on board. They have already been discussing ideas together.”
