Jamie Oliver has been voted the most trustworthy celebrity when it comes to believing star endorsements.

A poll of 2,000 people - carried out by UTalkMarketing.com - said they were most likely to buy brands endorsed by the celebrity chef.

This is good news for supermarket chain Sainsbury's; they pay Jamie millions of pounds to promote their goods.

Gary Lineker - who promotes Walkers crisps - came in second place, Myleene Klass came third, while Carol Vorderman made it into fourth place.

The poll also highlighted celebrities the public least trust.

And it looks like it's bad news for Brand Beckham, as Victoria was voted the star from whom we are least likely to buy.
