The Scottish singer-songwriter's latest single 'Don't Tell Me That It's Over' debuted on radio this week and the 22-year-old revealed that she is feeling apprehensive in the build-up to the record's release in March.
"It's really nerve-wracking actually and I feel pressure," MacDonald told the Daily Record. "I didn't feel under pressure when I was writing or recording the album which people normally feel pressurised with.
"But it's weird thinking how people will react when they hear it on the radio."
MacDonald continued to say that she has not yet confirmed a title for her new album, the follow-up to 2007's This Is The Life.
"The name that we are leaning towards is A Curious Thing - but we've not decided yet," she added. "I was just sitting going through all the new songs and really listening intently to the lyrics and that's a line from one of the songs that I thought sounded quite nice as an album title."
