Holly added that she much prefers being a pop star because it's more fun.
"It's always what I wanted to do. I did enjoy acting and being on Neighbours but singing is where my heart has always been."
Not even Holly knows how her character Flick will be written out of the soap.
"I hope she doesn't get killed off because I might need a job in about 12 months time," she said.
But if chart predictions are anything to go by, Holly won't have to worry about returning to Ramsay Street.
Pop experts say her single, released on Monday, is set to go straight in at number one.
