It looks like Usher is having a tough time mixing business with his personal life. According to the New York Daily News, the R&B crooner and his mother/manager Jonetta Patton parted ways professionally last November. "She walked away from the project because Usher had his girlfriend, Grace Miguel, all in the mix," a source said of Usher's rumored romance with the former Def Jam executive.

The source went on to say that Patton decided to end her business relationship with her son, in an attempt to retain their personal relationship. Usher and his mother were recently photographed spending time with the Grammy winner's young sons in Miami during Super Bowl XXIV weekend.

The shake-up in Usher's management is supposedly causing the delay of 'Raymond vs. Raymond,' Usher's sixth studio album. The self-indulging single, 'Papers,' in which the 31-year-old chronicled the cause of his crumbled marriage, failed to make a splash on the charts despite its controversial subject matter. The singer's label apparently then scrambled to release the follow-up singles 'Hey Daddy (Daddy's Home') and 'More,' while also pushing back the album's release date to March.

While his new management team is still pending, rumor has it Usher will sign with Randy Phillips, CEO of AEG Live and former manager to the late Michael Jackson. Usher and Phillips sat together during Clive Davis pre-Grammy party in Los Angeles. During the week's festivities, Usher also brought along Miguel who he was said to be very affectionate with.

His divorce to former wife, Tameka Foster-Raymond was finalized last year. The couple shares two young sons, Usher V and Naviyd Eli Raymond. 'Raymond vs. Raymond' hits store March 31.
