Julia Roberts Net Worth - In celebration of Red Nose Day, A-list Hollywood celebrities including Julia Roberts, Al Pacino, Arnold Schwarzenegger, Hugh Grant, Liam Neeson and Daniel Craig made a shocking revelation for a great cause.

Julia Roberts, whose net worth is listed as $140 million by The Richest, finally confessed a major secret she kept for years to commemorate Red Nose Day on May 21. Red Nose Day is a fundraising campaign dedicated for children and young people living in poverty in the U.K., Africa and in the United States.

In order to raise funds for poverty-stricken children in America and abroad, several celebrities collaborated with NBC and participated in a three-hour telecast Thursday night, Yahoo! Celebrity noted. And Julia Roberts, whose hefty net worth made her one of the world's highest paid actresses, proved that there's no price too big to pay when it benefits a great cause.

"Julia is incredible to work with and there's no doubt that she's a brilliant actress, but, um, I've just been directing her..." actress-director Jodie Foster revealed during the "Hollywood Secrets" segment of the star-studded Red Nose Day benefit on NBC. "And she has what I'd describe as a...distinctive voice? But it's not what I would associate with a Hollywood leading lady."

So, what is Julia Roberts' real voice? Will this affect her net worth value? According to E! News, the voice that came out of the 47-year-old "Pretty Woman" star's mouth was a deep man's voice.

Aside from Foster, Roberts' former costars, Hugh Grant from "Notting Hill" and Richard Gere from "Runaway Bride," also opened up about the surprising discovery they made while working with her. However, it seemed that Julia isn't the only one who's been hiding behind great editing and dubbing in her films. Time revealed that Grant, Liam Neeson and Daniel Craig also admitted that their voices were very different from what fans have expected.

While the American Hollywood stars admitted their secrets, British actors invaded the telecast with their new jobs. "Twilight" star Robert Pattinson was seen parking and crashing cars at valet while supermodel Naomi Campbell worked behind the camera. Former "American Idol" judge Simon Cowell directed the show, Orlando Bloom in the sound booth and many more cameos.

Meanwhile, Julia Roberts, who has been named as one of People magazine's most beautiful people in the world for 11 times, is an active supporter of several charities, Celebrity Net Worth reported. That's why it's not surprising if she joined the Red Nose Day campaign.
