The singer posted a 26-second snippet of 'Better Than I Know Myself', which he confirmed will be available to download in the US from December 20.
The track is the first cut to be lifted from Lambert's second studio album Trespassing, currently slated for an early 2012 release.
The star has worked with a range of producers on the upcoming record including Pharrell Williams, Dr Luke and songwriter Bonnie McKee.
Lambert recently described his new album as containing "party music, sex music, f**ked-up-relationship S&M music", adding that "every song explores something real".
