Janet Jackson promotes her book "True You: A Guide To Finding And Loving Yourself" at Barnes & Noble, 5th Avenue on March 19, 2011 in New York City.

*Janet Jackson is booked to attend the annual AIDS charity event Life Ball, to be held May 21 in Vienna — 30 years after the disease was first discovered, organizers announced today.

Jackson will be present in her capacity as representative of the Foundation for AIDS Research (amFAR).

“HIV/AIDS is a pandemic which requires our immediate and continued attention,” the singer says in a statement.

“Combination therapy has made HIV a maintainable disease, but sadly, there is still no cure and it continues to spread at alarming rates. HIV/AIDS is a continuing hazard, both in the Unites States and abroad.”

The Life Ball is held annually by AIDS LIFE, an independent non-profit organization that raises funds for people living with HIV.

Last year, the ball generated $ 2.1 million for AIDS charities.
