As you are probably well-aware, MAC scored big with this year’s Viva Glam collaboration by enlisting Lady Gaga and Cyndi Lauper as spokeswomen. They’ve already done the morning show circuit to promote the lipsticks which will be available March 15th. Every penny of the money you pay for a lipstick goes to the MAC AIDS Fund! Tomorrow, March 1st, Gaga and Ms. Lauper will be conducting a live interview from London, moderated by Sharon Osbourne, and you can watch it online!

MAC has been collecting questions from fans for the past few weeks, and tomorrow the Viva Glam ladies will answer them in this exclusive interview. All you have to do in order to watch is log on to the MAC Facebook page at 11am EST and click on the Ustream tab to watch the live stream of the interview. You can also watch a recording of the interview right after it ends if you can’t be watching when it’s live!
