Minogue, 42, British Prime Minister David Cameron, actor Liam Neeson and comic Ricky Gervais are among the stars that have recorded the new messages that are being sent to soldiers in Afghanistan.
Cameron praised the soldiers for the 'enormous sacrifices' they are making to keep people safe.
Minogue provided a starry message for the troops and said: 'We're thinking about you and send you lots of love.'
The messages will be read out during Jeremy Vine's Radio 2 special Remembering The Troops, which will be played at 1pm on December 23.
