Reports say Naomi Campbell was admitted to the Syrian-Lebanese Hospital in Sao Paulo on Sunday. In an official statement, the hospital said a doctor treating infectious diseases is the only one treating the supermodel.

"She was admitted into the hospital, she is in my care and that of Professor (Jose Aristodemo) Pinotti, but she did not authorize us to comment on the matter," Uip said.

The website Folha Online said Campbell underwent surgery yesterday but did not specify what surgery.
