Arjun Kapoor has discovered a quirky way to celebrate the five-year anniversary of his hit film Ki and Ka, in which he was cast alongside Kareena Kapoor Khan. Directed by R Balki, Ki and Ka follows a young, married couple whose relationship challenges the gender roles placed upon women and men in Indian society. As the film clocked five years, Arjun took to his Instagram account to share a picture of himself holding a mangalsutra and revealed that it was a piece of memorabilia from the film. He also expressed his desire for a sequel, asking Kareena to weigh in. Ki and Ka also stars Amitabh Bachchan and Jaya Bachchan in special extended cameos. In his post, Arjun also talked about signing Ki and Ka as a tribute to his mother, the late Mona Shourie Kapoor.
