NEW YORK — Lady Gaga and Cyndi Lauper dropped by Wednesday's Today Show, where they chatted about their participation in MAC's Viva Glam campaign to help women battle HIV/AIDS.

The two stars said they signed on to raise awareness about rising infection numbers in each of their age groups. Each singer will have her own shade of lipstick, with proceeds of the lipstick sales going towards AIDS charities.

"This lipstick is a gift and a message of I want you to aspire for a loving and monogamous relationship, and I want you to practice safe sex," said the 23-year-old Lady Gaga.

The "Bad Romance" singer also said she'd be honored to duet with her 56-year-old idol "in the spirit of fighting AIDS awareness."
