Hollywood actresses HEATHER GRAHAM and KRISTEN BELL are urging their fans to go barefoot for a day - to raise awareness of poverty-stricken children who can't afford shoes.

The stars are teaming up with American footwear firm TOMS Shoes and ditching their stilettos on 8 April (10) to prove how difficult it is to live without shoes - and they're hoping the campaign will encourage people to give generously to the cause.

Bell explains, "I'm going barefoot for one day without shoes to raise awareness about the impact a simple pair of shoes can have on a child's life. So join me on April 8. Take off your shoes and spread the word."

And Graham admits she's terrified about the prospect of walking barefoot, adding: "I'm pretty nervous about it because I live in New York City and it's really, really gross here."

Hairspray star Brittany Snow and documentary filmmaker Morgan Spurlock are among the other stars to take on the challenge.
