Throughout his American Idol journey, Heejun Han has been cracking jokes -- and while it's gotten him quite far in the competition, an exclusive new interview he gave to us is no laughing matter.

Idol Watch - The Top 9 Get So Emotional, Baby

Following Heejun's elimination (which he wasn't surprised by), the singer told our reporter that while he loves everyone who played a part in his season 11 experience, when asked who he will root for, Heejun told us, "I was rooting for Jeremy, Sharon or Erika ... but [that] didn't happen so I'm not gonna root any for now. I'm just gonna watch The Voice."

He also claimed that guest mentor Diddy was "kinda drunk when we were having our mentor session." And while Heejun lavished this week's guest mentor, Stevie Nicks, with endless compliments, he advised all famous future helpers, "You do not wanna be drunk when you're coming to American Idol session, OK?"

Naturally, the Idol publicist was less than thrilled by these comments and Heejun got pulled aside for a talking to after our interview. But that hasn't stopped him from bringing the one-man stand-up routine to Twitter this morning, joking with choreographers Tabitha & Napoleon that their Michael Jackson dance is what got him eliminated from the competition.
