"She and I are on great terms and support each other in our life's endeavors. We are both very happy but are now working in different areas of the business," he said in a statement to The Associated Press. "This is great for me because it means I now get to have my mother strictly as my mother with no added pressure."

Usher said he believed that by ending his professional relationship with his mother, it would bring them closer.

"At this time in my life, I am simply more interested in building the strength of my family. And in order to do that, I feel it's best to separate my business life from my personal life," he said.

This is the second major change this year for Usher, 28. In March, he announced his engagement to his longtime girlfriend, stylist Tameka Foster.

Rumors have swirled that Foster would replace Patton as Usher's manager, but the singer said: "She has no aspirations of becoming my manager or any other artist's manager."

Usher is slated to release the follow-up to 2004's "Confessions," which sold 9 million copies in the United States, later this year.
