Actor-producer Saif Ali Khan was caught and clicked with his pants down while shooting for his new film "Happy Ending". As directors Raj Nidimoru and Krishna DK shot "Happy Ending" at various locations in California, so to save time, Saif started changing at the shooting spot instead of going back to his vanity van. "Saif got so comfortable changing at the shooting spot that it almost became a familiar sight of him with his pants down, so I couldn’t resist taking a pic and Saif happily posed,” Nidimoru said in a statement. The movie also stars Govinda, Ileana D'Cruz, Ranvir Shorey and Kalki Koechlin. (Source: IANS)
