ShyneShyne held a Def Jam-sponsored conference call with DJs and journalists on Wednesday (August 11) to talk about new music and his upcoming album, but one of the rapper’s enemies popped up on the line … 50 Cent.

While no one may have realized during the call that it was Fif’ on the line, due to him posing as DJs and journalists to get on, the G-Unit General filmed himself making the call live and posted it on his website the next day (August 12).

In the clip, 50 is seen on the phone claiming to be a radio personality: “Shawn from Radio One,” he tells the conference call operator. He then asks: “What’s your real issue with 50 Cent?”

Despite the attempt, 50 was quickly disconnected, but called back from several phones to get back on the line. Later, he is seen yelling into the phone, pretending to talk to Shyne, spitting Mel Gibson-eque obscenities and declaring “you’re on an island. You can’t go to war on an island.”

The news of 50’s phone-crashing got back to Shyne, who responded in an interview with MTV, via Skype.

The Belize-born says he was shocked by Fif’s call, basically calling him a “stalker” who’s “desperate” for attention.

“Wow. That’s like an all-time low,” Shyne told MTV. “I didn’t know he was so desperate. He’s gone from confidential informant, witness-protection program dude, getting order [of protection] on motherf***ers. Now he’s a stalker. I was in shock. He called up saying he was ‘Jamal from Harlem.’ He didn’t call up saying he’s Curtis Jackson, Hawaii 5-0. He’s a busta. I can’t believe it. I can’t believe he would stoop to that low. Then again, a guy in the witness-protection program, he has no shame.”

Later in the interview, Shyne explained that he wasn’t aware that it was 50 Cent on the line at the time, until after the call was done.

“You know how it is. When you do these things, you always gotta expect a motherf***er to call and he might be disgruntled. We took it as another disgruntled person. ‘Cause you know, I don’t know what his voice sounds like. I don’t listen to nothing he do. If we on the yard, and they put his video on, they change the TV in the yard,” Shyne explained, referring to his recently completed prison stint. “I don’t jack that dude on no level. I don’t know what his voice sound like. But somebody at Def Jam caught him. He’s been reaching out to one of my generals in the street begging for peace. He caught his voice too. It was after the fact.

“I thought it was somebody who was having a bad day, who wanted to know the situation. It wasn’t until after everything was finished, motherf***ers at Def Jam was like, ‘That was Boo-Boo. That was Hawaii 5-0.’ I was like, ‘No. No.’ Then he put the out, like he was talking reckless. He’s a creep. Any of my comments have been honest comments. These dudes do anything, I don’t give a f***. It never bothered me. The fact that he’s sitting in New York, selling his Vitamin Water, listening to my Ustream. What the f***? You’re stalking me. Go take some steroids. Find something to do.”

Since posting the video of the call on his website, 50 hasn’t further commented on the incident.
