He says that his son's name is inspired by the success of Salman Khan's 'Ek Tha Tiger'.
"Salman bhai is synonym of Eid. Every year he gives us such great films on this festival and this year too he took our hearts away with blockbuster film 'Ek Tha Tiger'. When I got this very special gift on the auspicious occasion of Eid (Monday), I decided to give the name Tiger to my newborn son," Kumar said in a statement.
Salman's Eid releases - 'Wanted' and 'Dabangg' - have been blockbusters. Kumar has earlier directed films like 'Delhi Heights' and 'Jugaad'. His "Zilla Ghaziabad" features Sanjay Dutt and Vivek Oberoi.
