Renowned record label Island Def Jam and rap mogul Antonio “L.A.” Reid have reportedly terminated their affiliation with the chairman stepping down from his position.

According to a source from the label, Reid’s employment was terminated Monday (September 20) afternoon.

Record executive LA Reid during his tenure at Island Def Jam was responsible for heading over mega acts like Rihanna, Mariah Carey, Pink and Justin Bieber. Despite the fact that these artists are huge on popular consciousness, LA Reid still hasn’t been able to pull off any super sales. So… according to information on the entertainment wire, LA Reid got LET GO: “Def Jam fired L.A. Reid,” the source tells us. “He got the boot from the Board of Execs yesterday.”

Additional reporting suggests Reid may just be one of a few high-profile executives to lose their jobs.

Of course, the Def Jam folks are planning to keep the announcement very P.C. They will likely put out a statement saying things were cordial and/or mutual. But that’s def not the case, according to our source. Def Jam indeed did not renew his contract. We’re not privy to the details on the reasons behind the split. But we do know lots of politricks were involved. We also hear Sylvia Rhone, Executive VP at Def Jam’s parent company Universal, is next on the chopping block if Kelly Rowland’s next album doesn’t do well. So new blood will be riding in to Def Jam/Universal soon.
