The recently titled world’s highest paid celebrity, Taylor Swift, talked to and took photos with patients at Brisbane’s Lady Cilento Children’s Hospital, making their day brighter.

Young patients at Brisbane's Lady Cilento Children's Hospital have been given a morale boost with a secret visit from pop star Taylor Swift.

"Thank you Taylor Swift for dropping by the Lady Cilento Children's Hospital to give our patients and families a special surprise they'll never forget," the hospital wrote on Facebook. "They'll never 'shake off' the memories you made."

Slater Walker, a toddler who has been in hospital for the past three months following surgery for a brain tumour, spent 10 minutes with the star.

"It was really random. Just all of a sudden one of the nurses came around and said Taylor was there and she'd be popping by to see us," Slater's mother Bianca said.

"She thought my little boy was just amazing ... very bright and beautiful and he had a lovely smile," she said. "She laughed with him and high-fived him. It was really lovely. "I told her a bit about his condition ... she was so friendly and open and down to earth."
