Justin Bieber Mojo Radio Interview: Singer Gets Annoyed With Justin Timberlake Comparisons, Hangs Up (AUDIO)

Justin Bieber recently graduated from high school, but the 18-year-old still has a lot of growing up to do.

In a recent interview with a morning radio show, "Mojo in the Morning," Justin Bieber quickly became agitated when radio host Mojo commented on his similarities with former popstar Justin Timberlake.

“I hope you take this as a compliment,” said Mojo. “When I first got played the song by your record people, and this was months and months before it came out, they said 'Take a listen to this and tell me if you can tell me who this is.' I thought it was Justin Timberlake."

"When I heard 'Boyfriend' for the very first time,” he continued. “I thought it was Justin Timberlake's single.”

Unfortunately, Bieber didn't take it as a compliment. “Man, that’s crazy because our voices sound nothing alike," he said. "I mean, I'm not trying to sound like anyone. Saying I sound like someone else is not really a compliment. ... I think if you were to say 'I heard some Justin Timberlake-esque things in your sound,' I would take that as a compliment."

That represents change in Bieber's message. The singer admitted in May that he was "definitely" influenced by Timberlake on "Boyfriend."

"[Timberlake] was young, and he did it, and he was really amazing and had such amazing music," Bieber told MTV's Sway Calloway. "I can't say that I would be upset when someone compares me to him."

While Bieber has some conflicting opinions about his relationship with Justin Timberlake's sound, that's nothing compared to the reaction he had when Mojo decided to bring up Bieber's mother. Asked if he was afraid One Direction's Harry Styles might end up seducing his mother, given his penchant for older women, Bieber went on the offensive.

"I mean, definitely somewhat [I am friends with One Direction now]. They were in town a while ago and they came over and stuff, but, yeah, they're good kids," he said when asked about his friendship with the Brit boy banders, before adding, "I don't think you should worry about me [and my mom with Harry Styles] -- Worry about your mom, bro."

Mojo then noted that his mother had passed away, before Bieber hung up on the call. Now that's awkward.

Do you think Justin was justified in his response towards Mojo of “Mojo In The Morning” or do you think he was being a brat?
