Be careful when you're attending one of singer Rihanna's concerts. If a representative from MAC asks you to try her 'RiRi Woo' lipstick, just say "no thanks."
One fan, Starkeema Greenidge, 28, of Harlem, told the NY Daily News she tried the RiRi Woo lipstick at a MAC counter set up at a recent Rihanna concert. But 2 days later, the unlucky fan developed a cold sore on her lips which turned out to be herpes.
Rihanna has been plagued with rumors that she has herpes.
Greenridge said she's suing MAC to urge the company to be more sanitary with its products.
