"She has gained a lot of pregnancy weight," a source said. "When she gains weight, she normally does the Def Jam detox, but not now."

Live Daily holds another mention of this elusive Def Jam Diet:

Music's A-listers were on hand to celebrate L.A. Reid's 50th birthday at Nobu 57 in New York City, July 11th.

There was Jay-Z, looking so slim some started whispering about a "Def Jam Diet." One partier noted, "L.A. has lost a lot of weight. So has Jay, Jay's girlfriend Beyoncé, Mariah Carey, Reid's p.r. woman Laura Swanson and Def Jam publicist Jana Fleischman. It's amazing. It's like a whole new skinny company."
