Usher rushed to his wifes side after she suffered from serious complications from surgery:

Usher has canceled his performance at Clive Davis’ pre-Grammy party due to a family emergency, Access Hollywood has learned.

His wife, Tameka, is in Brazil and has experienced complications from plastic surgery. A neurosurgeon, Dr. Gabriel Hunt of LA’s Cedars-Sinai Medical Center, is on the way to South America.

A rep for Usher had no comment at this time. Josh Groban filled in for the R&B star at Davis’ annual event.

Foster, a 37-year-old stylist, recently gave birth to the couple’s second child, Naviyd Ely Raymond. The couple’s first child, Usher Raymond V, was born in November 2007.

The couple announced their engagement in February 2007, marrying on August 3 of that year.

As of Sunday evening, Dr. Hunt had arrived in Brazil.

Most women travel to Brazil for surgery because the procedures are far less expensive there. Usher is worth over $100 million, so why the hell was Tameka there getting a procedure done ????
