Ozzie singer Kylie Minogue is reportedly planning to duet with Madonna later this year, reports The Mirror. The Australian star will sing with the US performer during an ITV1 television special to celebrate her 25-year-long music career. A source told The Mirror: "There will be lots of duets. The plan so far is for a duet with her sister Dannii Minogue, Nick Cave, Jason Donovan and a finale featuring a duet with Madonna." The 'Can't Get You Out Of My Head' entertainer has already confirmed plans to release a Greatest Hits compilation album featuring "acoustic and orchestral versions" of her biggest songs. She has also teased plans to embark on an "anti-tour", which will see her take the re-worked versions of her most popular tracks around small venues instead of arenas. Kylie recently revealed that she is excited to listen to Madonna's upcoming album as she is a huge fan.
