One week after it was reported that Usher's new girlfriend, prompted him to fire his entire team, the music superstar has officially cut ties with his former management company.

Usher has made the jump from his longtime home Creative Arts Agency (CAA) and signed with rival William Morris Endeavors (WME), to support all aspects of his career. The 32-year-old was represented by CAA agent, Mark Cheathem since he was a teenager. Cheathem's other high profile clients include Oprah Winfrey, Brad Pitt and Will Smith.

Since dropping his platinum plus selling 'Raymond V. Raymond' album last year, Usher has seen a career resurgence, which not only earned him one hit single after another, but won him a trio of Grammy awards at this year's ceremony. Additionally, he is gearing up for a second U.S. run of his O.M.G. tour which originally kicked of last fall.

Upon filing divorce from former wife, Tameka Foster-Raymond, the Tennessee native hooked up with former Def Jam executive Grace Miguel in 2009. Unlike his marriage, Usher keeps a tight lid on his current relationship, only briefly referencing Miguel as his "partner in crime" for the first time publicly, during his acceptance speech at the American Music Awards last year.

This isn't the first time the father of two has fired his management. In 2007 he famously "retired" his mother, Jonetta Patton, as his manager amid both business and personal issues surrounding his marriage. He then hired manager Benny Medina, only to fire him and return to his mother following the dismal sales of his fifth release 'Here I Stand.'

At press time, Usher's label did not respond to a request for comment.
