After his last comedy flick, 'Humshakals', Nawab Saif Ali Khan is back with a bang. The actor steals the show in the first song 'Paaji Tussi Such A Pussycat' from his upcoming comedy 'Happy Ending'. Composed by Sachin-Jigar and sung by Amitabh Bhattacharya, Jigar Saraiya and Divya Kumar, ‘Paaji Tussi Such A Pussycat' is catchy, with lyrics that are as hilarious as Saif's look. The actor can be seen in a totally different avatar, featuring a beard and long hair with a hat as he strums on a guitar, surrounded by beautiful bikini clad women. We also get a glimpse of his beautiful co-stars - Ileana D’Cruz and Kalki Koechlin. Talking about the movie, in which he plays a writer, Saif says, “It is a genre I am comfortable with. Raj and DK (Raj Nidimoru and Krishna DK) have directed it in a slightly different way for me. Sometimes in the past I have acted a little loudly, and this one is quite subtle.”
