Ashley Judd is currently joining the line of celebrities who are hoping to make a difference in the world through humanitarian efforts, but admits she gets by with a little help from her music friend.

Ashley recently revealed her love of U2's music and help from Bono inspired her to get involved with charity work.

The brunette star has been working as a global ambassador for YouthAIDS in Central America and says she joined the fight against the life-threatening disease in 2001 after U2's Bono asked her to join his Project (RED) campaign.

The 38-year-old told PEOPLE magazine, "U2's music has been absolutely fundamental to my development as an activist. It's always great when Bono calls, for obvious reasons."

The actress is about to star in two new films, "Come Early Morning" and "Bug," and she is also releasing a documentary of her work in Central America on World AIDS Day on December 1.

"Ashley Judd and YouthAIDS: Confronting the Pandemic" also follows fellow YouthAIDS ambassador Salma Hayek during her work with communities in Guatemala, Honduras and Nicaragua which have been heavily effected by HIV and AIDS.

Ashley also revealed that helping to treat people in the hospices, clinics, brothels and slums taught her to take better care of herself.

She said, "I have so many more tools now. My self-care is really good."
