David Letterman banned guest Harmony Korine from the Late Show after he found the Spring Breakers director rifling through the purse of Meryl Streep. Letterman told the story on Monday (March 25, 2013) when prompted by guest James Franco, the star of Korine' latest movie.

The actor said he heard Korine was banned after pushing Meryl Steep backstage, though defended his director, saying, "Harmony is a very sane guy now -- a great artist and great person to work with. But I think he had a period where he was going a little off the rails, so maybe he was on something that night.

Letterman proceeded to correct Franco on the incident, saying, "I went upstairs to greet Meryl Streep and welcome her to the show, and I knock on the door ... and she was not in there.And I looked around, and she was not in there, and I found Harmony going through her purse. True story. And so I said: 'That's it. Put her things back in her bag and then get out."

Korine is perhaps best known for his movie 'Gummo' those has caused a stir with his latest flick Spring Breakers, which stars Selena Gomez and Vanessa Hudgens as college students who are pulled into a world of drugs, sex and violence after meeting a shady character played by Franco.
