Selena Gomez's Apple TV+ documentary, My Mind & Me, is a brutal one-and-a-half-hour look at the star's mental health struggles over the past six years, particularly following her bipolar disorder diagnosis.
But the biggest headlines to come from the film, unfortunately, relate more to what received only a small mention: Gomez's life-saving kidney transplant in 2017.
In September of that year, Gomez revealed she had received a kidney from her friend, How I Met Your Father actor Francia Raisa. The pair met in 2007, and they instantly became best friends.
Prior to the transplant, Gomez had been diagnosed with lupus which was causing her kidneys to fail. The demand for kidneys is high for transplant patients, so Gomez later explained that it was going to take years for her to find a donor.
When it was discovered Raisa was a perfect match and agreed to donate one of her kidneys, it saved Gomez's life.

Over the years, the pair have often shared public messages of love and support. But last year, things became seriously messy. And it was all to do with speculation that their friendship had ended following the transplant.
