Ariana Grande has proven time and time again she's always there for her fans, no matter what. And this time, she's letting the world know she's mourning the loss of a beloved Arianator, once again leading the charge when it comes to uniting her fandom during a heartbreaking moment.

Katie, just 14 years old, was a huge Ariana fan who according to one of her friends on Twitter was set to attend Ari's Dangerous Woman Tour too. But Katie was diagnosed with cancer and unfortunately passed away yesterday. That when many of the singer's fans rallied on Twitter to share Katie's story in hopes that Ariana would see it.

After many tweets which fans posted along with the hashtag #RIPArianatorKatie, Ariana did see this message. She took to her Instagram Story to share a photo of Katie looking as happy as ever posing with her beloved Ariana merch while she was in the hospital. "rest in peace Katie my baby my heart is with you," the songstress wrote on the photo.

It truly means the world to Ariana's fans knowing she took the time to hear them out and celebrate Katie. Ari has been rather quiet on social media lately with her last Instagram post letting the world know she's hard at work on new music, but obviously she is still there for her fans when they need her. Ariana has had to deal with an immense amount of tragedy after there was a horrific bombing at her concert in Manchester that resulted in the loss of 22 fans and more who were injured. But Ariana didn't sit back: she held a benefit concert for the victims and re-started her tour up, proving that music does have the power to unite, heal and most importantly send out hope and love even during the darkest of times. Ariana's fans have never left her side and clearly, she'll always be there for them too.

Rest easy, Katie.
