Though B-Town was in festive mode yesterday, Alia Bhatt and Ranbir Kapoor were sweating it out. The duo was spotted outside a dance class in Khar. The actors have started prepping for the next schedule of Ayan Mukerji's Brahmastra.

Alia was spotted carrying some sheets of paper, while RK had a cup of coffee. Both were casually dressed and appeared tired. Looks like they had practised for some elaborate dance moves for the mytho-fantasy, which has Big B as co-actor.
