Former NBA star Dennis Rodman was reportedly thrown out of the Time Hotel in New York City for loudly telling guests about his friendship with North Korean leader Kim Jong-un.

The 51-year-old recently made a controversial trip to the country to meet Kim, whom he described as "awesome", just weeks after North Korea carried out a nuclear test as a warning to the United States.

"He was at the bar at Serafina for three hours," the New York Post quotes a witness as saying. "He kept saying what a nice guy Kim is, and how Kim just wants to talk to President Obama about basketball. He was waving around a signed copy of the dictator's huge manifesto, telling everyone they should read it.

"Dennis was making a total jerk of himself. He wouldn't leave, and he wouldn't let anyone talk to him about shutting up, or what an oppressive country North Korea is. Eventually he had to leave the bar."

Rodman visited North Korea with members of the Harlem Globetrotters.
