Monster power!

When she's not busy starring opposite Justin Timberlake on Saturday Night Live or promoting her brand-new album "Born This Way," Lady Gaga channels her philanthropic spirit into global efforts.

In addition to a limited-edition lip gloss and lipstick released in February, Mother Monster and MAC have just launched an interactive project to promote "Glam This Way", a new campaign part of MAC's Viva Glam initiative that was established by the brand in 1994 to support men, women, and children affected by HIV/AIDS around the world.

For a limited time, little monsters can log onto, upload a photo of themselves (which glamorously turns into a sequin) to the site, and share the "Glam This Way" message through their social networking platforms like Twitter and Facebook. The more awareness they spread, the bigger their photo will appear on the Viva Glam website. Plus, the star's stylist and BFF Nicola Formichetti will print all of the fans' images on a couture masterpiece, which Lady Gaga herself will wear this fall. How's that for fame?

It doesn't seem as if Gaga will have any problems getting her fans on board to make an impact -- the 25-year-old star has 35 million Facebook likes and 10 million Twitter followers. These two stats, plus her impressive tour sales helped land her the title of Forbes magazine's World's Most Powerful Celebrity.
