why not ? Even saw Novak in Sofia how drunk whisky whole night with his bodyguard.It was when he took a part in a movie. He is sick but smoke a CIGARETTE maybe because he enjoys himself.Who knows but i do not believe he is smoker
What does this have to do with anything?
So he had a little bit of fun while filming a scene in a movie... I would too.
By the way, I thought you had said you took a photo of this night and would share it with us. Still waiting.
