Freelance photographer Dara Kushner says she was injured when Love bodysurfed through the crowd during her performance at a Manhattan music venue late Thursday night. Kushner was treated for a bruised and swollen neck at Beth Israel Medical Center and released.
It wasn't immediately clear if Kushner would press charges.
At another performance that began in the early hours of Thursday, police say Love hit Gregory Burgett, 24, of London, Ky., in the head with a microphone stand as he watched the beginning of her show at a posh Manhattan nightclub.
Burgett needed three staples in his head, and Love was arrested on misdemeanor charges of reckless endangerment and third-degree assault. She was released later Thursday morning.
Her arrest capped a day that also included flashing David Letterman - and lifting her shirt at least six times - on the talk show host's late-night television show.
Love, 39, is also facing drug charges in California, where she was arrested in October for allegedly trying to break into the Los Angeles home of a former boyfriend.
Police later called to Love's home allegedly found painkillers when Love was taken to a treatment center for a drug overdose.
