Justin Bieber NEVER Met King Kevi: Alleged Best Friend, Selena Gomez 'Lover' In Malibu Rehab for 'Sizzurp' Abuse, 'Talks to the Biebs Everyday,' Bromance A Total Lie?

King Kevi - the aspiring rapper who allegedly befriended Justin Bieber and even tried to romance the "Believe" crooner's ex, Selena Gomez. Kevi recently checked himself into the infamous Passages Malibu rehab center for abusing the dangerous concoction "sizzurp." In an exclusive interview with RadarOnline, the young party animal reveals that he talks to the Biebs almost everyday and that the pop megastar has been "very supportive" throughout this entire ordeal. But according to Bieber's crew, the "Beauty and the Beat" superstar's never even MET Kin Kevi. Apparently, the entire bromance is a lie... which sorta makes sense. Have fans seen any photos of Bieber chilling with this "best friend" who apparently lived with him for a good chunk of time? Read on for more details...

King Kevi made headlines earlier this year for "shacking up" with Bieber as he tried to jump-start his own music career. He even apparently attempted to "romance" Selena Gomez AND Kate Upton:

King Kevi sat for a full exclusive interview with RadarOnline on Thursday (June 13) while in rehab - he claims he was the "party ringleader" of Bieber's posse. "I'm the main party guy in the group... [the] ringleader for getting it for everybody, because I had the hookup." Apparently Kevi used to bring "60-70 girls" to the parties he threw at Bieber's house, and "Justin started liking that."

Now that he's in rehab, the Biebs remains a close, supportive friend.

"I talk to him everyday... He actually sent me some new headphones," Kevi says. "He sent me a necklace too that's dope with diamonds and gold on it."

As for "hooking up" with the "Spring Breakers" beauty, Kevi wouldn't comment. He does say he might not be spending much time with Biebs in the future, "Justin's not really supposed to be seen with me."

But according to Gossip Cop, all of this is a total lie. Bieber apparently doesn't even know King Kevi!

One of the singer's reps reveals that he “never met him before... [Bieber] doesn’t know who he is.”

Kevi's "bromance" with the Biebs was all staged. The insider believes Kevi might be totally "delusional" - even a "complete liar."

Gossip Cop confirms that several L.A. clubs banned King Kevi after he demanded VIP treatment by dropping Bieber's name... even at times when the singer was out of the country.

Crazy stuff... do readers think King Kevi is "obsessed" with a friendship that doesn't even exist?
