The 29-year-old and his wife Una, who is a member of five-piece girl band The Saturdays, are already parents to two-year-old daughter Aoife Belle.

Una confirmed the news on her Instagram page with an image of her daughter wearing a T-shirt that read, 'I'm going to be a big sister'.

The couple married in June 2012.
