It was on this day in 2014 that Allu Ayaan was born and Allu Arjun became a proud father.  Marking his beloved son's birthday, the 'Ala Vaikunthapurramuloo' actor has written a love letter sort of tweet to his son.  

"I used to think 'What is love?' all my life. Many times in the past, I had felt strong feelings but I was not sure if it was love. But after you came into my life, I now know what LOVE is. You are the LOVE. I love you, Ayaan. Happy Birthday My Baby," Bunny tweeted out.

Sneha Reddy, the Stylish Star's wife, posted a family pic of Ayaan cutting the cake as his cute sis, Arha, looks on.
