New Delhi: With his latest film Sivaji- The Boss still rocking the box office even six months after its release, this birthday could be a special one for Tamil superstar Rajinikanth who turns 57 on Wednesday.

While fans across the state are gearing up to celebrate their Thalaivar's (leader) birthday, the star is set to go into hiding.

"Rajini sir, in all probability, won't be in town this year too. Usually, he doesn't meet his fans on his birthday. It will be no different this year," a source close to the actor informed.

However, his fans have plans to celebrate the day in a grand manner.

"This birthday is special for both our Thalaivar and us as Sivaji is set to complete 200 days in over 50 theatres in a week's time. So, we have planned to celebrate the day in a great way," said J Ramki, co-founder of Rajinifans.com, a portal dedicated to fans of the superstar.

He said the site would carry out many welfare activities around the world.

"We will organise a grand function and a music nite to celebrate Rajini's birthday in Dubai and Malaysia, where there is a sizeable chunk of Tamil population."

Elsewhere in Tamil Nadu, fan clubs will celebrate the day by distributing sweets, performing special prayers at temples and churches and undertaking various philanthropic activities.

In Chennai too, the fans are set to start the day by performing poojas at temples, donating blood and providing food to orphanages in the city.
