Scottish rock singer Annie Lennox has become a spokeswoman for the UN agency fighting HIV/AIDS.
She was appointed as UNAIDS' goodwill ambassador on Wednesday, and pledged to address the "daily brutality faced by millions of women and girls" suffering from the disease.
The 55-year-old musician achieved fame with The Eurythmics, whose song Sweet Dreams reached No 1 in the United States in 1983.
She has since performed as a solo artist and spoken out on political issues. Her SING campaign raises awareness of AIDS-infected women in southern Africa.
Lennox said: "If we are to end the cycle of human devastation triggered by the AIDS epidemic, we must address the rights of women and girls, and challenge their second-class citizen status, which puts them at greater risk of HIV."
