Chelsea Handler isn't holding back when it comes to naming the star she had one of her worst interviews ever with. It's Justin Bieber! And boy, does it sound awkward!

Handler, 40, tells Variety that during each of several times she had now 21-year-old Bieber on her show Chelsea Lately, he flirted with her. Heavily.

Ew!

"Justin Bieber maybe [was my worst interview], because he was trying to flirt with me and it was so uncomfortable,” she told Variety at the Sundance Film Festival. "Like, that’s his schtick. He would come on and flirt with you and you just felt like a child molester right away. And I didn’t want to feel that way."

Yikes. What's worse, it wasn't just her.

"I think he does that with everybody," Handler said, adding that it didn't work on her at all. "I was not sexually attracted to a child."

Wait til you see him coming on to Chelsea in this clip of one of their interviews! It's cringe-worthy, to say the least.

It's not the only time the Biebs has had eyes for a much older woman. Recently he was said to be hooking up with Kourtney Kardashian, but has since moved on with someone closer to his age, 19-year-old Hailey Baldwin, a model and the daughter of actor Stephen Baldwin.

Oh, Justin. We're looking forward to the day when you finally grow up!
