It seems like he still hasn't learned his lesson: James Franco stirs controversy once again by posting a shocking picture of himself on Instagram.

The 36-year-old actor shared yet another selfie via the social networking site on Thursday night (May 1), and this has to be one of his most shocking photos yet. The image shows a nearly naked Franco standing in front of the mirror in his bathroom, only wearing a pair of boxer briefs with his one hand inside.

James Franco, who claims to be addicted to social media and taking selfies, is apparently doing some sort of social experiment. However, he clearly realized that he might have gone too far this time with his inappropriate snapshot, as he took it down just an hour after posting it.

Last month, the "Pineapple Express" actor already had a scandal related to Instagram, involving a 17-year-old girl. He found himself in trouble after trying to pick up a young female follower. Although he apologized on Wednesday, Franco told Howard Stern on his radio show that he had been a gentleman.

"Here's a thing, the way that the news wants to do it ... they make it like, I'm perusing young woman," he said. "I'm not going to high schools looking for dates. I'm leaving my work, and they're coming there."

"I was a gentleman, I said, 'Do you have a boyfriend,' and her response was, 'Not when you're around.' So that to me sounds like, 'Okay, she's interested,'" he continued.

James Franco also said it was not the teenage fan's fault that it became a scandal. "Here's what I'll say in her defense -- I don't think she posted it knowing what was gonna happen," he added. "I was like anybody, just trying to meet somebody. It's just that my dirty shit gets put out internationally."
