Ajith is turning 45 on Sunday, May, 1. The "Vedalam" star, as always,  has refrained from celebrating the birthday in public and is expected to be with his family on his special day.

But it has not stopped his fans from celebrating his birthday as they cut cakes and distribute sweets in his name. When it comes to the online fans, they started wishing the actor soon after the clock ticked 12 am on Sunday. They have created trends on Twitter with multiple hashtags, chief among them being: #HBDDearestThalaAjith.

However, the fans are a little disappointed as Ajith's new movie, which was supposed to take off on May 1, has been delayed for some reason. The film, which is currently referred to as "Thala 57," is written and directed by Siruthai Siva and the cast-crew is yet to be revealed. The regular shooting of the flick will reportedly start in June.

Meanwhile, many celebrities, including Malayalam superstar Mohanlal, have wished Ajith on his special day. Here, we bring to you the tweets posted by them:
