COMEDIAN Peter Kay admits he knows more about heartburn than being a heart-throb in behind the scenes footage from his hilarious Warburtons advertisement.

The Bolton funnyman is the latest star to join forces with the bakery for one of its ad campaigns.

'Pride and Breadjudice' first aired on national television on Saturday, in the commercial break during The X Factor.

Based on an adaptation of the true story of Warburtons beginnings as a family business, Peter tells the love story of Thomas and Ellen Warburton in his own much-loved comedic fashion.

It takes inspiration from the nation's favourite literature and on-screen lotharios including Mr Darcy and Poldark.

The latest video goes behind the scenes and shows the making of the advert, at 16th century estate Lyme Park in Cheshire.

Peter has the crew in stitches as he is seen joking with company chairman Jonathan Warburton.

He tells viewers: "Similar to previous Warburtons adverts where ideas are being pitched to Jonathan Warburton — mine is called Pride and Breadjudice so I'm pitching that idea to Jonathan, hoping that he will take it to Hollywood.

"I have to be honest with you, I don't know too much about being a heart-throb but I do know a lot about heartburn."

The advert, for Warburtons Seeded Batch loaf, is not the first time the Bolton business has called upon a famous face to promote its products.

Can you spot all the jokes in Peter Kay's Warburtons advert?

In 2015, Hollywood star Sylvester Stallone appeared in advert, The Deliverers, part of which was filmed on Bolton Town Hall steps.

Later that year, The Muppets promoted Warburtons’ Giant Crumpets.

Speaking of why he teamed up with Warburtons, Peter said: "I've grown up with them all of my life, so personally it felt like a good fit.

"The other major factor was that the previous advertising campaigns featuring The Muppets and Sylvester Stallone have been brilliantly produced and most importantly very funny so I presumed that would something they'd want to do again and do as well."
