Rajinikanth "requests his fans not to celebrate his birthday and avoid keeping banners and posters," his publicist said in a tweet.
When contacted, the publicist said the decision not to celebrate the birthday was taken in view of the demise of Jayalalithaa.
The 'Kabali' star turns 66 on December 12 and usually his birthday is celebrated in a grand manner by his fans.
Last year also, he did not celebrate his birthday following the torrential rains in Chennai and neighbouring districts that led to a deluge.
The AIADMK government in Tamil Nadu has announced a seven-day State Mourning from December 16.
