As Varun Tej celebrates his birthday today, Sai Dharam Tej can't wish the birthday boy enough. "Wish you a very happy birthday ra @IAmVarunTej love you and wish you have a successful year ahead ?????? God bless," he says.

In doing so, the 'Intelligent' hero shares an old pic of himself and the 'Tholi Prema' hero. Whoever sees the pic can't stop admiring the physical transformation undergone by the two over the years. There was a time when Varun Tej was fatty and his lean and fit look is a world of a difference.

Interestingly, the two Mega heroes might see a clash at the box office, on Feb 9, when both 'Intelligent' and 'Tholi Prema' are scheduled to release. (Note: Only the latter made its release date official).
