Usher’s wife reportedly suffered cardiac and respiratory arrest during a liposuction operation, is reporting.

Tameka Foster was due to undergo the cosmetic surgery at Sirio-Libanes Hospital in Sao Paulo, Brazil, last Friday but fell seriously ill when she was being anesthetized for the procedure.

She was then induced into a coma for 24 hours, and is now said to be recovering, the gossip website alleges.

A spokesman for the hospital refused to comment on the allegations published by Brazilian news website G1, saying: “The family has demanded total privacy. The hospital is barred from giving any information.”

The website reports that it has been claimed U.S. neurosurgeon Gabriel Hunt, who works at the Cedars-Sinai Medical Center in Los Angeles, flew to Sao Paulo to help treat Tameka over the weekend. He left on Monday but refused to comment, it adds.

Usher cancelled concerts in the U.S. and rushed to his wife’s side as soon as she fell ill.

His spokeswoman Simone Smalls has not released details on Foster’s illness, only saying: “Tameka is in stable condition. Her husband is with her at the hospital. The family requests privacy at this difficult time.”
