According to the Daily Telegraph, the parents looked to the Kardashians for inspiration, naming their first-born, Saynt Myles.
The newspaper also suggests the reasoning behind the unique spelling of the name, using a ‘y’ instead of an ‘I’, could be due to the fact that the name Saint can’t be officially registered with NSW Births Deaths and Marriage after they banned the use of certain names.
James and Myles, who have been married since 2011, confirmed they were expecting their first child together in August, three years after the actress battled Hodgkin’s lymphoma.
The couple have managed to keep all details of the little ones arrival top secret, and only ever share photos on social media with his face out of view.
"It's really wonderful,” the first-time mum told Fairfax back in February. “Things are going really well and we're all really content and healthy and happy."
