Westlife are going head to head with Kylie Minogue in the first big UK chart battle of the year.
Shane Filan from the Irish band says they are confident of outselling her.
But he thinks it will be tough to dislodge Enrique Iglesias's song Hero from the number one single spot.
Westlife's new single World Of Our Own coincides with Kylie's new release In Your Eyes.
Shane said: "We are great fans of Kylie and are looking forward to meeting her at the Brits.
"But we reckon we will sell more singles than her. Our real problem may be with Enrique Iglesias who is still so strong at the top."
