Wilmer Valderrama - Valderrama & Belle Film All-Star Psa For Chile

WILMER VALDERRAMA and CAMILLA BELLE have recruited a string of screen stars, including ROSARIO DAWSON and DEMI LOVATO, for a new campaign to benefit earthquake-stricken Chile.

The charitable pair founded IAmTheCountry.com to encourage American citizens to donate to the relief effort in the South American country, which was hit by a devastating earthquake in February (10).

And they've convinced their showbiz pals Dawson and Lovato - as well as Topher Grace, Twilight actress Nikki Reed and Alexander Skarsgard - to film a public service announcement (PSA) to back the campaign.

In a post on their website, Valderrama and Belle write, "We are joining forces to bring light to and raise awareness of the many ways YOU can help the country of Chile in their moment of desperation.

"This inspired us to produce a PSA to use as a platform to show the simple ways we can all help the organisations that are providing assistance to the people of Chile."
