Of all the people whom Chelsea Handler’s interviewed, one stands out as the worst: Justin Bieber! Chelsea dished that Justin’s excessive flirting was beyond uncomfortable, and made her wish the interview never happened!

Chelsea Handler, 40, told Variety while at Sundance on Saturday, January 23 that Justin Bieber, 21, is the worst guest she ever had the displeasure of interviewing on Chelsea Lately! The talk show host and star of Chelsea Does explained that Justin has a habit of um, being very flirty, and she just couldn’t take it from someone who was that young. It wasn’t sexy to her, it was really, really icky!

Chelsea had Justin on her talk show a number of times during its run, first interviewing him in 2009, when he was just a young teen! So you can understand her squeamishness when it came to a kid trying to cozy up to her! “Justin Bieber maybe [was my worst interview], because he was trying to flirt with me and it was so uncomfortable,” she told Variety. “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.”

She added, “I think he does that with everybody.” So in typical Chelsea fashion, she did not hold back on this! In his 2010 appearance on the show, when he’s practically just a baby (listen to the voice and look at that hair!), he amps up the flirting with Chelsea hard! Though you can’t see her reactions in the clip above, you can tell she’s cringing; he refers several times to a date that he had asked her on during his previous appearance. “You know last time I was serious about that date. It never happened,” Justin says, later adding, “I’ll be able to drive [my new car] on our date tonight.” * hair flip * Damn!

Chelsea was asked if Justin’s flirting tactics ever worked on her: “I was not sexually attracted to a child. Thank you for clearing that up on camera,” she told Variety. Yeah, Justin should probably stay away from her!
