Viva Glam?

Lady Gaga wore lace boyshorts under an all-lace bodysuit, adding a facemask, which blossomed into a flower on her head to the MAC Viva Glam Launch in London on Monday night. The eccentric star, was joined by the other face of the cosmetics company, 1980’s icon Cyndi Lauper, who sported an interesting look as well.

Cyndi’s hair was wildly curled, as she left her hotel in London to attend the lipstick launch, with steaks of black mixed into her blond tresses. More demurely dressed than Gaga, the pop singer definitely evoked a goth-glam look.

Sharon Osbourne was also on hand for the festivities. What was Ozzy’s rocking wife wearing? Check out the gallery in Style to find out.
