Malaika Arora Khan is a hot favourite with item songs, and her husband also plans to cast her soon. Arbaaz Khan is busy working on his next venture 'Dolly Ki Doli' with Sonam Kapoor. And recent reports suggested that Arbaaz is keen on having wifey Malaika overboard for a sizzling item song. While the actor turned filmmaker considers Malaika his lucky charm, he is still undecided about casting his wife. 'Dolly Ki Doli' will see Sonam Kapoor in a de-glam role of a con woman. Saif Ali Khan too has a cameo in the film.
