New Yorker Starkeema Greenidge claims she caught the virus from a sample of MAC's RiRi Woo lipstick, which was given to her at the singer's concert in Brooklyn on May 7. Greenidge's lawyers claim the sales assistant "didn't use a fresh or new lipstick tube, but rather one that had been used for other patrons" and two days after the show, Greenidge found a cold sore on her lips.

Greenidge says, "This is going to happen over and over again if nothing is done. I wasn't able to work for two weeks. It cost me a lot of money."
