Jon Stewart's Selena Gomez fan club membership has run out. And it's all because of Justin Bieber. Seth Rogan eggs him on.

Jon Stewart took a shot at Selena Gomez during a May 7 interview with Seth Rogen on "The Daily Show." Stewart said that he's no longer a Selena fan after Gomez's on again off again relationship with "douchebag" Justin Bieber.

Justin Bieber and Selena Gomez's romance hit late night talk shows now as Jon Stewart went on a rant about the former Wizard of Waverly Place. Stewart told the Daily Show audience that Gomez has changed since she started hanging around with Justin Bieber.

Jon was chatting with his guest, the comic actor Seth Rogen, who has bashing Justin Bieber during promotions for his new movie "Bad Neighbors." Rogan said he met the Biebster and took an immediate "hate" to him.

Jon Stewart complained that Gomez used to be a great model for the kids until she got involved with Justin Bieber, saying "I have young children. And [Selena] was the winner of the family wizard competition on Wizards of Waverley Place."

Jon Stewart isn't a fan of Bieber either. He admitted "They were engaged in a battle for four years and she ended up winning. My kids really respected that victory."

Seth Rogan encouraged the funny outburst by asking "And it's diminished by her association with Justin Bieber?"

Stewart pondered, "How do I explain that to them? She was a wizard and now she's hanging out with a douchebag."

Selena Gomez and Justin Bieber split in December 2012, but rumors began to flow that they're back together after they hit the Coachella Music Festival and Gomez visited Bieber in a Miami studio where he's recording new material.

Justin Bieber finally responded to Seth Rogen's recent Bieber bashing. During an interview with Howard Stern, Rogan called the 20-year-old pop star "obnoxious", "ungrateful" and "a piece of s***" after he met the young pop idol.

Rogen said, "When I met Zac Efron, one of the most endearing things is that he recognized that he as a Disney star, and I as a man in my late 20s/early 30s, would f**king hate him. Why wouldn't I?"

Roggan continued "Justin Bieber had zero percent of that. No humility, no awareness, no sense that, 'Since I appeal to young, young people, maybe a grown man who works in comedy doesn't give a s**t about me? And maybe I should act in such a way that maybe this isn't the greatest experience of his f**king life to meet me?' And I just remember thinking he's a piece of s**t."

Bieber took to Twitter to respon "Seth Rogan (sic) sorry I didnt bow down when I asked 2 meet u was probably a bit shy and didn't want to be over the top but still. love ur movies."
