"Happy to be back," the 29-year-old captioned a video of herself in the gym.
"I honestly look forward to sharing with you, soon my journey through these past several months as I have always wanted to do with you. Until then I want to publicly thank my family and incredible team of doctors for everything they have done for me prior to and post-surgery," she captioned a photo of the pair resting in their hospital beds.
"There aren’t words to describe how I can possibly thank my beautiful friend Francia Raisa," she continued. "She gave me the ultimate gift and sacrifice by donating her kidney to me. I am incredibly blessed. I love you so much sis."
Gomez and The Secret Life of the American Teenager alum have been friends for years. "Francia is a wonderful friend with a huge heart. They’ve thought of each other as sisters, and beyond their obvious bond through work and womanhood, they also share a lot through their faith and being Latina," an insider previously told Us. "Francia is incredibly supportive and would provide a shoulder to cry on for any friend in need. She really is a wonderfully special person."
