Akshay Kumar is proud that his son Aarav bagged the first degree black belt in kudo, a Japanese martial art sport.

 

It's a #SonDay all the way! Honestly I can't express my happiness, I've received the best gift ever today. My son started training when he was just four years old. And today, after nine years of hard work he got his 1st degree black belt in Kudo, Okinawa and Goju Ryu Karate Do! Some joys cannot be expressed in words, this one tops the list. But I'm feeling so proud, had to share it with you all ðu00c2u009fu00c2u0098u00c2u0080 #overwhelmed #cantstopsmiling #proudfather
