Miley Cyrus is teaming up with video sharing website YouTube to help raise awareness of a number of charities.
The Hannah Montana star is urging her online fans to submit clips showcasing their favoured organisations - and the top three promos will earn a spot on the YouTube Video Volunteers section homepage later this month (Jun10).
Cyrus says, "I think it's just really important to always give back in as many ways as you can. There are so many ways to get involved.
"If you're watching this video, you probably have all the tools you need to get involved and make a difference. I'm asking you to participate in YouTube Video Volunteer Program. Create a video about a service organisation that you really care about."
