UPDATE: Tameka reportedly went into cardiac and respiratory arrest during a liposuction procedure.

An unexpected matter forced singer Usher to cancel a performance over the weekend. But unlike in the Rihanna/Chris Brown situation, this issue was not police related.

The 30-year-old had been slated to sing at Clive Davis’ pre-Grammy party on Saturday evening. But after calls from both Usher and his mother, the record mogul was forced to deliver the bad news: the performance was going to be scrapped due to a “serious illness in the family.”

According to Access Hollywood, Usher’s wife, Tameka Foster, experienced complications after undergoing a plastic surgery procedure in Brazil. Although it’s not known which specific treatment the 37-year-old was supposedly seeking, Foster gave birth to their second child together back in December. Access claimed that a neurosurgeon from LA’s Cedars-Sinai Medical Center was being flown to the South American country to assist.

It has been rumored that Foster will appear on the second season of The Real Housewives of Atlanta.
