Janet Jackson is taking it easy following her bout with the flu. The pop star, 41, who paid a visit to Cedars-Sinai Medical Center in L.A. Monday night after falling ill, has decided to cancel an upcoming Saturday Night Live appearance originally scheduled for Saturday, her rep confirms to PEOPLE.
"The main prescription to get over this flu is rest – and that's what she has to do," her rep says. No replacement has been announced yet.
