Grammy award winning singer Usher canceled a Pre-Grammy appearance late Saturday to rush to Brazil where his wife Tameka Foster-Raymond suffered “complications from plastic surgery.”

A source close to Usher’s camp told Sandrarose.com last night that Tameka suffered “an emergency related to the plastic surgery,” but she is “fine now.”

According to published reports, neurosurgeon Dr. Gabriel Hunt of LA’s Cedars-Sinai Medical Center was flown to Brazil to consult on the case.

The most likely reason that a neurosurgeon would be consulted is if the patient fails to wake up from the anesthesia. This type of emergency can occur when the patient receives too much anesthesia and not enough oxygen during the procedure.

Artists and adult entertainers routinely travel to Brazil to have plastic surgery performed by skilled surgeons at upscale clinic/resorts which offer both privacy and a luxurious setting for the patient to recuperate.

Brazilian doctors are also favored for the cheaper rates they charge.

Usher and Tameka have two children together. Naviyd Ely Raymond, was born in December 2008, and the couple’s first child, Usher Raymond V, was born in November 2007.
