Get your tissues ready — we have some truly heartbreaking news.

Jalene Salinas, the beautiful little girl who stole the hearts of Taylor Swift and the internet at large, has passed away. She was just four years old.

You may remember Jalene's story, which went viral after news broke that the little girl's dying wish was to dance with her idol to "Shake It Off." Supporters used Twitter hashtag #ShakeItOffJalene to promote Jalene's wish. When Taylor heard the story, she caught up with the little girl via FaceTime.

Jalene died around 7:45 PM Sunday, according to San Antonio's KENS5 Eyewitness NewsShe battled an aggressive form of brain cancer for nearly a year.

"Shake It Off" has become an anthem for anyone undergoing a hard time. Case in point: The Children's Hospital of Philadelphia lip-synced the tune in a new viral video recently posted on the hospital's Facebook page. 

The video features both the hospital's patients and staff singing and dancing to the song, which takes on a whole new meaning in this context. The video is heartbreaking and uplifting at the same time.

Our thoughts are with the family of Jalene Salinas during this incredibly difficult time. We are so thankful this sweet little girl was able to see her final wish come true. RIP Jalene.
