The 'Bodies' singer's main homepage features a single portion of his head, along with the date "03.09.12".
His official Facebook and Twitter pages also posted the image, with the caption: "Countdown: Day 1."
The date is most likely connected with his upcoming new single, which may either receive its premiere airing or a download release on the specified date.
The new single has yet to receive an official title, but several publications such as the Daily Mail have stated that both his new single and album will be called 'Vertigo'.
Williams was recently seen filming the video for the single in East London, which included him in full medieval armour on a horse.
He revealed last month that his upcoming ninth studio album is near completion.
The Take That star is also expecting his first child with wife Ayda Field in the coming weeks.
