Lucy and Ryan's news comes just weeks after the couple experienced a terrifying ordeal with their son Roman, who was rushed into hospital following a sudden emergency.
The doting mum had previously posted a heartbreaking photo of her baby son hooked up to an IV tube in hospital. Detailing their horrifying experience, Lucy wrote: "As some of you may have noticed we haven't been on social media lately. "Just over a week ago I found Roman blue in his cot - probably every parent's worst nightmare. Without going into too much detail it ended up with Roman being transferred to St Mary's London intensive care being put on a ventilator. Thankfully we are now all home and Roman is back to his cheeky self."

She added: "Although mentally we as a family may never fully recover, we feel extremely blessed to have our special boy home in our arms and it has truly opened our eyes to all the hardworking superheroes working in our hospitals who dedicate their lives to helping others and how extremely lucky we are to have these incredible medical services free for us all in the UK."
