Ariana Grande is back in the U.K. and eager to spend time with her fans in the wake of the suicide bombing that killed 22 and injured 119 more during her Manchester concert on May 22.

On Friday night, the star visited the Royal Manchester Children’s Hospital, where many of her young fans are being treated.

Adam Harrison and Lauren Thorpe, who were injured in the blast along with their 8-year-old daughter Lily, shared photos of their little girl embracing Grande. “All we can do is thank Ariana,” Thorpe tells PEOPLE. Adds Harrison, “What Ariana Grande did tonight was so selfless and amazing … Lily looked on cloud nine.”

Of their bootleg Grande apparel in the photos, Harrison tells PEOPLE, “We bought official merchandise at the concert but was ruined (ripped/blood) so [we] had to throw it away. But an unofficial shirt seller outside the venue donated the t-shirts he didn’t sell to the kids in hospital. I apologized to Ariana that we had unofficial merchandise on, and explained the story. She laughed at and told us not to worry at all!”
