Abby Lee Miller is in a desperate battle against cancer—but one of her loyal former Dance Moms kids has brought a smile to her face in the hospital!

Loyal JoJo Siwa, 15, visited Miller's hospital bed on Sunday, May 27, and the ex-reality TV coach posted a sweet photo of them together.

Miller, 51, captioned the shot, "So glad @itsjojosiwa came to visit me today! The whole fam was there to wish me well! Thank you to the Siwa Family for all the beautiful gifts and real popcorn from the movie theater too! I'll let JoJo post the big Surprise she arranged! Thank you all from the bottom of my ❤!"

While JoJo's Instagram photo and caption didn't reveal any particular surprise, the teen wrote with a similar shot, "Got to see my favorite today!❤ Abby you have changed my life for forever, I am so thankful for everything you have done for me (Table manners, how to survive in a plastic bubble, and more)! Thank you for letting us come by and visit you today! I love you. FOREVER.❤⭐"

Miller was lying in her hospital bed and her wrist had medical tags around it as she affectionately touched pal Siwa's wrist
