The joke refers to a previous instance where Selena's operation was used for comedy purposes during an episode of the Saved By The Bell reboot, in which two characters debated over who Selena's donor was, as well as featuring graffiti which read "Does Selena Gomez even have kidneys?".
Following the Good Fight episode, Selena took to Instagram this week to blast the attempts at comedy as "tasteless".
She wrote on her Instagram Story: "I am not sure how writing jokes about organ transplants for television shows has become a thing but sadly it has apparently. I hope in the next writer's room but when one of these tasteless jokes are presented it's called out immediately and doesn't make it on air. My fans always have my back. LOVE YOU. (sic)"
As of the time of writing, The Good Fight has not issued a statement about the joke, nor has its broadcaster, Paramount Plus.
After the initial joke in Saved By The Bell, bosses of the reboot eventually edited the episode and removed the scenes, and an apology was issued by NBC.
They said in a statement: "We apologise. It was never our intention to make light of Selena's health. We have been in touch with her team and will be making a donation to her charity, The Selena Gomez Fund for Lupus Research at USC."
