Lady Gaga & Cyndi Lauper Put Their Lips Together

Will these two singing sensations hit the recording studio together? We sure hope so...

Lady Gaga and Cyndi Lauper singing together? We think that could be kind of genius.

In fact, Lauper even says she could see it happening one day.

"Everybody is on her right now, so I would wait and do it when things calm down a bit," Lauper told me earlier today. "She's very busy. She likes to jet in, do it, and leave and go on to the next thing she's gotta do. I think it's great."

Lauper witnessed firsthand the busy craziness that is Gaga's life right now...

The two star in M.A.C Cosmetic's latest Viva Glam campaign for the MAC AIDS Fund. "I've always wanted to be a Viva Glam girl," Lauper says.

Sales of new lipsticks created by the singers for the makeup giant (light coral red from Lauper and light blue-pink from Gaga) benefit the fund, which has raised more than $150 million in the fight against HIV/AIDS since it was started in 1994.

"You can abstain or be monogamous—which I think is a good idea—but some people aren't," Lauper says. "That doesn't mean you don't have to be safe though...Be aware. Be educated. Put the lipstick on and use it as a reminder."

P.S.: It's not like Lauper isn't busy herself. Not only does she appear on the upcoming season of The Celebrity Apprentice, but she's going to be releasing a blues album, is working on her memoir and is also writing the music for a musical stage adaptation of the movie Kinky Boots.
