Charlotte Church is making £100,000 by teaming up with Gary Lineker on a Walkers crisps TV advert.

The singer will begin filming on Thursday at a secret location, reports the Sunday Mirror.

A source told the newspaper that Church is a fan of the Lineker series of commercials. "Charlotte turns down loads of ads and promotions but she loves crisps and likes the ads," he explained. "So why not?"

The star was also impressed by the advert's funny script. "Charlotte thinks the ads are really funny. They are sexy but with humour, which is just the type of woman Charlotte is," the source commented. "She can't wait for filming to begin."
