Psy Describes ‘Gentleman’ Release as the ‘Worst Time Ever’

Psy already made history with his new video for 'Gentleman,' and even though he makes it look easy, that doesn't mean the viral K-Pop superstar didn't put in a slew of work on the single and its promo. The man busts his butt -- and he's not always happy about it.

"I honestly changed this song so many times until the very last moment," he gushed to MTV News. "I was not excited, I was terrible; I was so nervous!"

Psy's reputation isn't lost on him either, and it put a lot of pressure on him to succeed and prove his haters wrong. "My only goal was to avoid being called a one-hit wonder. So that was a very nervous moment right before the premiere; and in two weeks, with 230 million views, I'm not a one-hit wonder. I'm really happy and relieved about that!"

Still, leading up to the release was no picnic.

"I released it on April 12, and on April 13 I had a huge concert in Korea ... so that week, it was like hell," he admitted. "On Friday, I had to release the single, and on Saturday, I had to release the video and I had to do a 50,000-person stadium concert. And that same week, on Monday and Tuesday, I did the shooting [of the 'Gentleman' video]. And I was done with the shooting on Tuesday, and on Wednesday, Thursday, Friday, we were editing, and I was rehearsing and I was memorizing all the choreography. So that week was like the worst time ever in my life."

But it paid off!
