A New York woman claims she left a Rihanna concert with more than a kissable pout.

Starkeema Greenridge, 28, says she contracted herpes after a visit to a MAC pop-up shop at Rihanna's Brooklyn concert, reports the New York Daily News.

The Harlem resident has filed a lawsuit against MAC, the cosmetics company that manufactures Rihanna's makeup line. The pop star's RiRi Woo lipstick was the product Greenridge says was applied to her lips by a rep at the May 7 concert at the Barclays Center.

Greenridge says the MAC employee told her to "press her lips together and spread the lipstick around." The suit also asserts the reps didn't use new lipstick tubes between concertgoers testing the product during the show.

A couple of days later, Greenridge says a cold sore appeared on her lip and she was later diagnosed with herpes by a doctor.

“I wasn’t able to work for two weeks. It cost me a lot of money,” Greenridge told the Daily News. “This is going to happen over and over again if nothing is done.”

Greenridge is seeking an unspecified amount in damages, citing the "mental anguish and emotional distress" the cold sore caused her.

MAC has yet to comment on the claim.

Rihanna announced the deal to create a beauty collection for MAC Cosmetics in February. In an interview with WWD the singer said she has always wanted to create her own makeup line.

"I’ve been using MAC on tour for such a long time it was a natural fit for me," she said. "I have always loved makeup, and I always said that if I do it, I want to do it with a credible brand.”

Her RiRi Woo lipstick was the first product released from her MAC collection. The lipstick went on sale May 2 and sold out in a few hours.
