The singer will release Heaven in the US sometime in 2012 and revealed that she may have to adjust her accent so American fans can understand what she is saying.
Ferguson is quoted by The Sun as saying: "Maybe they'll get subtitles on my interviews if I go over there. The Beatles did OK though, didn't they? They had to change their accents a bit. I'll work on that."
The star revealed that she is adjusting to fame in the UK, but insisted that it will be nice to head to North America where she will not be recognised on the street.
She added: "I was out in Liverpool and couldn't put my drink to my mouth because of people taking pictures. And Liverpool is the place where I'm used to being able to get on with things."
Ferguson's first studio album Heaven reached number three on the UK chart on Sunday (December 11) after facing competition from Amy Winehouse's posthumous release Lioness: Hidden Treasures.
