Ursher is probably crawling on his hands and knees, snotting, begging for his mom to come back and be his manager. I guess he didn't think his career would "retire" with his mom. He went from selling 1.1 million copies in a week (Confessions) to 433,000. LMAO @ the fact Plies sold more than him.

“People have been telling Usher to listen to his mother,” says a source. “Nobody knows how to sell him better than she does. Usher can be stubborn. But he may be ready.”Some claim Usher pink-slipped his mom because she failed to show proper deference to his stylist-turned-girlfriend-turned-wife, Tameka Foster. But now that Foster has given her a grandson, the two ladies are said to be getting along better. (source)

Serves him right for getting too big for his britches. He let Maneka dickmatize him and now he's paying the ultimate price for it. I guarantee he'll watch his setup next time.
