Justin Bieber wants his friends to stay away from Selena Gomez.

Justin is currently on tour and isn't pleased that his best buddies are spending time with his ex-girlfriend while he's away, according to Radar Online.

Specifically, the Biebs is unhappy about his pal King Kevi chilling with her, as King Kevi was spotted leaving Selena's house one night last week.

“Kevi and Selena are friends," says a source. "There was a party that night with 15 or 20 people – just a little kick back – and they were hanging out, smoking hookah with some buddies.”

However, Justin hadn't been aware that King Kevi would be hanging out with Selena, so when Justin found out through the media, he angrily called Kevi on the phone and spoke his mind.

“Justin was pissed,” the source continues. “He said, ‘Yo, why were you kicking it with her? I thought you and I were homies.’ He doesn’t think they’re hooking up but doesn’t want his closest friends partying with her."

“Kevi told him there was nothing going on, and they’ve gotten over it, but Justin is always suspicious something sexual is going to happen,” the source adds.

However, Justin might be right to suspect that Kevi is interested in being more than friends with Selena. 

“Kevi thinks she is smoking hot, but he is like Justin’s brother, so [he] has to keep it low-key,” explains an insider.

“Honestly, I don’t know when he’ll see her again," the source goes on. "She’s going to do press for her new album, so Kevi is going to keep a bit of distance for awhile.” Probably for the best, no?

Justin can at least rest assured that Selena's parties are much tamer than the parties that go on at his own house. Selena apparently "barely ever drinks when she has parties," says the source.

Long story short, it looks like Justin's friends just need somebody to love as much as he does.
