Catherine Zeta-Jones is due in Wales on Friday to rename a children's hospital in Cardiff.
The Oscar winner and mother of two opened the Children's Hospital of Wales along with actor husband Michael Douglas in 2006.
The hospital treats around 25,000 young patients and 75,000 outpatients each year and provides life-saving treatment to critically ill youngsters, as well as expert skills for those with conditions requiring specialist care.
The return visit will be the actress' first since 2010, when she attended a function to celebrate the 10th anniversary of children's charity Noah's Ark Appeal, which is the hospital's official charity.
It was set up in 2000 to raise £5 million for a new facility for ill youngsters needing specialist treatment, with a funding drive launched by then 14-year-old singer Charlotte Church.
