Days after returning to the United States from his polarizing trip to North Korea, Dennis Rodman checked into a rehab facility for his struggles with alcohol. Rodman's agent Darren Prince didn't disclose where the former NBA star was staying.

"His drinking escalated to a level that none of us had seen before. When he came back [from North Korea], I discussed with him on a personal level how concerned I was. We sat down and decided for him to go to rehab. It is a 28 or 30 day facility."

Rodman, who has always attracted the media spotlight, was the target of widespread ire for his basketball mission to North Korea and his budding friendship with North Korean dictator Kim Jong Un. During his most recent visit, Rodman crooned an uncomfortable and very public rendition of "Happy Birthday" to the North Korean leader, lost his cool during a CNN interview, and even criticized Kenneth Bae, an American citizen currently being held captive in North Korea on bogus charges.

Rodman ultimately released a statement to apologize. He explained that his actions were caused by his drinking and admitted that he was probably not the ideal diplomat for such high-level statecraft.
