Bridget Jones' Knickers on Auction Block

The famously large underpants worn by film character Bridget Jones are to be auctioned off to raise cash for some of London's most famous green spaces.

The large, white underwear was worn by Renee Zellweger in her role in "Bridget Jones's Diary" and prompted the comment, "Hello, mummy!" from Hugh Grant, who played her suitor, Daniel Cleaver.

The underwear, signed by Grant, will be auctioned off at a charity dinner next week for Britain's Royal Parks Foundation, it was announced Friday.

Organizers hope the dinner will raise $185,000 for the Royal Parks, which provided the setting for scenes in the second film in the series, "Bridget Jones: The Edge of Reason." One scene in the movie took place in a fountain at Kensington Gardens; another was shot at Regent's Park.

The Royal Parks are some of London's most popular, and also include Hyde Park, St. James's Park and Green Park.
