The 'Love On Top' singer posted a cryptic message to her official website on Wednesday, highlighting a particular date in August.
"Leave Your Footprint On 19 August 2012," read the post.
Beyoncé has maintained a relatively low profile since giving birth to daughter Blue Ivy Carter in January, making only a handful of public appearances, including a comeback concert at Atlantic City's Revels casino.
Earlier this month, the star picked up two BET Awards for 'Best Female R&B Artist' and 'Video Director of the Year'.
Beyoncé's husband Jay-Z recently praised his wife, calling her "the best performer in the world".
