Who is the worst celebrity to interview? According to Chelsea Handler, it’s Justin Bieber.

The comedian, who hosted more than 1000 episodes of "Chelsea Lately" between 2007 to 2014, told Variety that the pop star tried to hit on her during the interview.

“He was trying to flirt with me and it was so uncomfortable,” 40-year-old Handler said.

“Like, that’s his schtick. Like he would come on and flirt with you and you just felt like a child molester right away. And I was like, I don’t want to feel that way.”

Although she singled out Bieber, Handler said she’s had “so many” bad interviews with famous people over the years.

“When you interview celebrities, they’re so guarded so many times, they can’t reveal anything.”

Handler now has a new four-episode documentary series on Netflix called "Chelsea Does," in which she discusses marriage, Silicon Valley, racism and drugs.
