A few hours after a loopy Late Show appearance in which she lifted her shirt to expose her breasts at least six times, rocker Courtney Love was arrested early Thursday for allegedly throwing a microphone stand and striking a man in the head.

The 24-year-old man was taken to a hospital in stable condition, police said. Police said they were charging Love with reckless endangerment and third-degree assault after the 2:30 a.m. incident at New York's Plaid nightclub. Messages left for representatives of Love Thursday weren't returned.

Love, who is facing felony drug charges in California, lifted her olive shirt several times on David Letterman's CBS talk show.

Her back was facing the camera when she exposed herself while making an entrance. She then stood atop Letterman's desk, sang a few bars of "Danny Boy," and offered the host an up-close viewing. The video was altered so a profile of her breasts could not be seen.

She alluded to actress Drew Barrymore, who similarly exposed herself to the talk-show host.

"Very sweet of you," Letterman said. "We're going to lose our liquor license."

Love later lit up a cigarette - defying New York City's strict anti-smoking laws - and asked Letterman, "Are you going to cut this because I'm smoking?"

"That won't be the reason we cut anything," he replied.

Letterman looked profoundly uncomfortable with Love's scatterbrained performance, but he did get the last word. He was looking to cut to a commercial, but Love insisted he ask her one more question.

"How much do you weigh?" Letterman said.

Love looked shocked. She didn't answer.
