Irish Nadine now lives in Los Angeles, meaning her son or daughter will grow up with a US accent and using words such as 'garbage' instead of 'rubbish'.
Despite being well into her first pregnancy, this has only just dawned on Nadine - who expressed her shock on Twitter.
Last night (26 November), she simply stated: "It just dawned on me my baby is going to say things like soda."
In August, Nadine revealed to her fans that she is pregnant with her first child, sharing a picture of herself on Twitter with the caption: "I'm having a baby!"

However, she kept the identity of the tot's father a secret for weeks, before finally confirming that it is her off-now-on boyfriend, American footballer Jason Bell.
Nadine recently said: "When I said I was pregnant I thought, 'Why's everyone wondering who it is?'
"Then I remembered, 'Oh yes, that's right. I do stuff on TV and people are confused. So this clears it up!'"
