Nicki's post featured an array of photos of a smiling Miyah, as well as a pic of the two gals sitting together. She wrote: "I can't believe this little angel is gone. When I met her she was recovering. Sending love to her mother and family and John. This is heartbreaking. She was so full of life. #RIPMiyah."
The "Anaconda" singer is not the only star mourning Miyah's loss. Washington Wizards' point guard John Wall commemorated his friendship with her as well.
John reached out to Miyah earlier this year, and was the main reason Nicki met the girl in the first place. The 24-year-old basketball star took up the charge on social media to make the meeting happen, spreading the hashtag #HelpMiyahMeetNicki on Twitter.
John spent time with Miyah as she battled cancer, and wrote her name on his shoes throughout the season. John played Monday night, after learning of Miyah's passing, and helped the Washington Wizards beat the Boston Celtics 133-132 in double overtime.
After the game, John broke down in tears on the court when asked about his friendship with Miyah, and her passing.
He also posted a memorial to Miyah on Twitter, writing: "If you were blessed to meet and get to know Miyah you know how special of a little girl she was. I'm saddened by the news but I know that she's in a better place. Keep her family in your prayers. I'll definitely miss my buddy. Rest In Peace Miyah."
