Amanda Coley’s dreams of seeing the boy band she loved growing up were crushed on Aug. 1 when she was diagnosed with cancer.
“We found out about three weeks ago that [Coley] had leukemia,” Kingston, 25, tells PEOPLE of her sister. “She was like, ‘So I can’t go to the Backstreet Boys concert?’ That was the first thing she said. She was crying. Both of us are huge fans. She told me I should go. But I said, ‘I’m not gonna go if you don’t go!’ “
After being admitted to the hospital and undergoing treatment, her sister decided to plan small surprise party in her hospital.
“It was my idea to go up there and play music and eat junk food,” Coley says. “[Coley’s] son Mason made these little invitations and we asked the nurse to pass them out to the other nurses on the floor. We just wanted them to stop by and say hi.”
But the nurses decided to go above and beyond. A group of them danced into Coley’s hospital room clapping and singing songs by the Backstreet Boys. Kingston says they performed three numbers as Coley sang along.
“I was crying! It was really emotional. We didn’t expect it. We were just in awe,” Kingston says. “Amanda danced with them! She was in heaven. She said it was really cool and emotional. She shed a couple happy tears.”
