The singer was spotted in East London earlier this month shooting a music video for his new track, which is expected to debut early next month.
Williams has now posted another image of his face cast in clay, which is slowly being put together piece by piece in the run-up to an announcement on September 3.
The performer recently told fans that he was deciding on the tracklist for his ninth studio album, which indicates that he is planning to release the collection before the end of 2012.
Williams also surprised a fan by performing new track 'Losers' on Chatroulette back in July.
The new set will serve as the follow-up to 2009's Reality Killed the Video Star which reached number two on the UK chart and has sold over 1.5 million copies in Europe.
