Amitabh Bachchan wishes Rajinikanth on birthday

Megastar Amitabh Bachchan has extended birthday wishes to Tamil superstar Rajinikanth, who turned 62 today.

Bachchan also wished good health to Rajnikanth, who fell ill during the shoot of Raana and was taken to Singapore to recover earlier this year.

The Sivaji star is recuperating from a kidney ailment and is away from the city to take rest at an undisclosed location.

"Happy birthday Rajni! Wishing you good health and many more achievements in life... happiness and prosperity always," Bachchan posted on Twitter

Bachchan, 69, who worked with him in films like Andhaa Kanoon, Geraftaar and Hum, called Rajini a humble human being.

"Its Happy Birthday for Rajnikant... friend and colleague and a humble gentleman, despite his immense following and cult iconic figure," Bachchan added.

Rajini's only appearance in a film this year was in the Shahrukh Khan-starrer Ra.One.
