Francia Raisa was in no mood to pose for the cam Friday on her film set.

Photogs were out in force to get a pic of the woman who saved Selena Gomez's life by donating a kidney.

Selena revealed this week her best friend donated the kidney several months ago, after hers were failing.

Francia was on the set of her new TV show, "Grown-Ish."

TMZ broke the story ... Francia actually had a harder time recovering than Selena.  She was not able to engage in any serious physical activity for several months and her diet is now restricted and monitored.
