A 10-year-old Santa Rosa girl named Danica has been battling a brain tumor and she is also a HUGE fan of Meghan Trainor's.
Danica is known as Sonoma County's "Princess Warrior" and she has lost feeling in her leg and arm.
Hospice volunteers have been with her family over the past week.
Danica has always loved Trainor and says her music helped her get through past chemo treatments, so you can imagine how excited she was to hear from Meghan Trainor on Twitter!
Hugs to you Danica! Stay strong!
