A source from the unit reveals, "The movie has come to an end and was suppose to wrap up on August 14, but got delayed by a couple of days which has kept the actor's beard on.
Ranbir has given his dates and has to shoot a song video for Wake Up Sid and needs a clean look for the film. Thus, he has to make sure he finishes his shoot of Rocket Singh to remove his beard."
The source continues, "Director Shimit is very particular about Ranbir's natural beard and doesn't want him to don a fake beard either.
Even the lead actress Gauhar Khan has colored her hair dark blonde for the character of the film. Ranbir will finish his shoot by next week and few patchwork of Gauhar will be remaining then to be shot."
"The actor himself has got exhausted with the beard and wants to remove it ASAP. This is probably the first time Ranbir has kept such a grown beard on him for such a long period. He has been making public appearances too in this avtaar of his" adds the source.
