When an Australian fan’s health woes kept her fromKaty Perry‘s concert, Katy Perry came to her instead.

Grace Moores, 8, who is fighting a brain tumor, was gifted tickets to Perry’sWitness: The Tourconcert in Adelaide for her birthday,according toThe Advertiser. But she had to miss the show because of an operation last week.

Her sister, Tiana Moores, 16, used Twitter to reach out to Perry and share Grace’s story, noting that Grace “has been battling all year” and has “been Katy’s biggest fan since she was 3.” More than 20,000 retweets helped the 33-year-old pop star hear about Grace.

On Tuesday, Tiana’s online outreach paid off. Perry spent an hour with Grace, her parents, and her four siblings at their home in Banksia Park.

“When Katy arrived out the front, Grace was a bit shell-shocked. She was just in awe. The smile on her face was just priceless,” Grace’s mother, Marie Moores, recalled toThe Advertiser. “She’s definitely walking on cloud nine this morning. It’s definitely given all of us a bit of a lift.”

Marie said that Grace gave Perry a tour of her bedroom and that Perry played three songs of Grace’s choosing with two band members.The BBC reportsthat Grace selected “Roar,” “Firework,” and “Chained to the Rhythm.”

“Katy is the most down-to-earth, genuine person you could meet,” Marie continued toThe Advertiser. “Just for someone like her to take that time out of her day to make all Grace’s dreams come true has just put a whole new spin on the really crap year we’ve had so far.”

After the visit, Tiana tweeted, “GUYS WE DID IT! @katyperry just visited grace! She’s [truly] amazing and such a sweet person this was [truly] amazing!”
