And Sarah, who is of European and Costa Rican descent, took to Instagram last week to share a photo of growing belly during the last weeks of her of pregnancy, writing: '10 days until we meet #BabyJames.'

'I'm excited, happy and enjoying every second of my pregnancy. Can't wait to meet James! #NFG #37weeks [sic].'
