The siblings are expected to be at the finale of the show to promote their films, said a source. While Kareena will come to spread a word about Madhur Bhandarkar's "Heroine", Ranbir will be part of the show to promote his film "Barfi!"
It will also be a rare time when two films will be promoted on one platform! One guesses there's no sibling rivalry here.
Jokes apart, there's been a strong buzz that the two actors will be seen in their first on screen pairing in a Zoya Akhtar project. They will reportedly play brother and sister in a project, which is said to be an autobiographical tale on Zoya and her brother, actor-fillmaker Farhan Akhtar's life.
