The vocal powerhouse announced on Tuesday that she will be pitching in to help the medical staff at New York’s Cedars-Sinai, where the singer had been under treatment in the past. Turning to Twitter, Selena wrote: "So thankful for every single medical professional who is putting their health on the line to take care of others.” "I’m donating to @CedarsSinai as they are low on masks and ventilators. They’ve taken such good care of me so it’s my turn to show my gratitude,” she added.
