http://www.eonline.com/uberblog/marc_malkin/b99008_ushers_wife_in_stable_condition_after.html Usher is dealing with a family crisis. Record mogul Clive Davis shocked guests at his annual star-studded pre-Grammys party Saturday night when he announced that the R&B superstar would not be performing as planned. Davis, president of Usher's J Records label, announced that the entertainer and his mother phoned earlier to cancel his rehearsal and subsequent performance at the Beverly Hilton because of a "serious illness in the family." Reps for Usher declined to comment or elaborate on the sad news, but a source close to the 30-year-old denies rumors that his wife, Tameka Raymond, 37, had died following plastic surgery. Access Hollywood reports, however, that Raymond did suffer complications from a cosmetic procedure in Brazil. The couple have been married since August 2007 and have two children. Tameka formerly worked as Usher's stylist. UPDATE: Usher's reps say the R&B singer cancelled Grammy plans because wife Tameka Raymond is in a Brazilian hospital after "suffering complications from routine surgery." Foster is in stable condition and Usher is with her at the hospital, according to the reps. No further details are being released.
