French actor Olivier Martinez will be playing soccer against singer Robbie Williams in an upcoming charity match to raise money for the United Nations Children's Fund (Unicef). Martinez, the boyfriend of pop queen Kylie Minogue, will be joining an all-star line up including Joseph Fiennes, Damian Lewis and TV chef Gordon Ramsay in a game that will pit English stars against the 'Rest Of The World' for UK television channel ITV1. Host Declan Donnelly is looking particularly looking forward to the competition between Williams and Ramsay, saying "They're both ultra-competitive, so it should be a pretty feisty match. "I just want Gordon to call me 'big boy'. I love when he calls everyone that."
