The "Bad Liar" singer was spotted out and about in New York City on Friday, a day after sharing with fans that she had recently undergone the procedure after her longtime pal, Francia Raisa, graciously donated her kidney.
In her post, the 25-year-old pop star put out a call to action to visit the Lupus Research Alliance's website, which the organization tells ET has spurred nearly half a million dollars in donations, when pooled with the work Gomez has already done to bring support to the group, which leads the fight against the disease that impacts so many lives, including her own.
“Selena’s openness and strong emotional connection to her worldwide audience has brought extraordinary awareness to a disease that is typically overlooked,” the organization's president and CEO, Kenneth M. Farber, said in a statement. "As a result of her encouragement to visit our website, LupusResearch.org, to learn about lupus, our phones have been ringing off the hook and our website traffic has soared."
"Selena has supported our organization in many ways, donating a portion of tickets sales for her last concert tour to the Lupus Research Alliance and requesting donations to us on the occasion of her birthday, as well as yesterday’s announcement," Farber added. "Together her appeals have raised almost $500,000 for research funded by the Lupus Research Alliance.”
