Ariana Grande has often tweeted about her love for her 90-year-old grandfather Grande and in a series of emotional tweets last night, July 4, Grande seemed to indicate that her grandfather was not doing too well.

She also shared this sweet photo of her with her mother and grandfather at the hospital in Florida.

Grande's grandfather was previously diagnosed with malignant cancer earlier this year, but in early June, she announced that he had finished treatment and beaten the disease, hailing him as an "inspiration" and "hero."

After Grande's tweets about her grandfather last night, her fans took to Twitter to show her support with the hashtag #PrayForGrandpaGrande, which trended throughout the night on Twitter and into the morning.

We, too, are pulling for you, Grandpa Grande.
