"I think I have the ability to both make hits and help make artists," Rotem said in a statement. "I don't want to overstate things, but I'm very excited about my forthcoming work."
The first artist signed to the Beluga Heights is 16-year-old Miami-based rapper Sean Kingston, who is in the studio with Rotem working on his debut album.
"The deal was designed so that J.R.'s relationship to Epic will be what Dre's relationship is to Interscope. He'll be the musical ear and face of the label," said J.R.'s manager Zach Katz who is co-owner and CEO of the label.
