Miley Cyrus backing Sean Penn's Haiti charity

Miley Cyrus is hoping to give Sean Penn's Haitian relief organisation a big boost by asking her young fans to pledge their support to the charity.

The former Hannah Montana star has filmed a public service announcement to encourage donations and raise awareness of the struggles Haitians face following the country's devasting 2010 earthquake.

Other stars including Zooey Deschanel, Edward Norton, LL Cool J and Eric Dane have also filmed promos for the J/P Haitian Relief Organization, which was founded by Penn immediately after the tremor.
