Authors to read at benefit
J.K. Rowling, Stephen King and John Irving will read selections from their own works during two benefit performances at Radio City Music Hall this summer.
It will be Rowling's first visit to the U.S. since 2000. The Harry Potter creator is a resident of Edinburgh, Scotland.
King, author of Carrie and other horror tales, came up with the idea for the benefit. He called it "a dream come true for me."
"An Evening With Harry, Carrie & Garp" will be held Aug. 1-2.
The performances will benefit the Haven Foundation, which helps performing artists whose accidents or illnesses have left them uninsured and unable to work, and Doctors Without Borders, a humanitarian group that delivers aid in more than 70 countries.
Jane Fonda and Salma Hayek are pressuring the Mexican government to end violence against women in the Mexican border city of Ciudad Juarez, where more than 300 women have been murdered over the past 12 years.
The actresses spoke Monday ahead of a Tuesday evening performance of The Vagina Monologues. They were joined at a news conference by the play's author, Eve Ensler.
Mexican officials say 340 women have been slain over the last 12 years in Ciudad Juarez, a city of about 1.3 million. But human rights groups say the number of women killed is much higher.
All proceeds from Fonda and Hayek's performance were to benefit organizations aiding women and girls in Ciudad Juarez.
Judd advocates AIDS awareness
Ashley Judd, whose screen credits include roles in De-Lovely and Kiss the Girls, said campaigning on behalf of AIDS awareness has changed her life.
The 38-year-old actress, who is world ambassador for the Washington-based YouthAIDS group, was in Honduras as part of a weeklong visit to Central America.
YouthAIDS promotes sexual abstinence as the only 100 percent-safe way to prevent AIDS, as well as monogamy and correct condom use.
