James Franco on nude selfies: "It's what the people want"

David Letterman addressed James Franco's propensity for posting provocative pics on his Instagram account.

James Franco's answer? “To me it’s just a fun thing, it’s something I don’t put a ton of thought into, but it gets a lot of attention,” he said.

“It’s not like I’m putting that on billboards. Ostensibly Instagram is for my fans. But now all the bloggers are on there so they’ll just take it and use whatever they want.”

And for that, James, we thank you...
