Myleene Klass's visit to the Royal Victoria Hospital in Belfast is to feature as part of a BBC series on the National Health Service.
The show Matron, Medicine And Me: 70 Years Of The NHS, documents how the service revolutionised healthcare in the UK since its birth in 1946.
To mark the anniversary, Lucy Alexander, Myleene Klass, Oritsé Williams, Miriam Margolyes and Eric Knowles go on a journey to meet the doctors, nurses, porters, cleaning staff and carers who have kept the service going against all the odds, and the patients whose lives have been saved by them.
Former popstar Myleene visited the Royal and scrubbed up to work with the nurses. Her mother Magadalena, from the Philippines, worked in the NHS for 40 years.
And Myleene got a chance to see first hand the invaluable role of staff from overseas do for the service.
The series begins on BBC One on Monday at 9.15am and is on every day of that week.
