Sonu rehearses to avoid Farah's whip!

Actor Sonu Sood is bold and brawny, but he is scared of "Happy New Year" director Farah Khan, known to be very strict on the set.

"Only way to save (myself) from Farah's whip is to rehearse religiously for the song to be shot after three days #HNY. On the job," Sonu tweeted Tuesday.

"Happy New Year" is a multi-starrer, featuring actors like Shah Rukh Khan, Abhishek Bachchan, Boman Irani, Vivaan Shah and Deepika Padukone.
