Alia Bhatt who is going to turn 25 on 15th March is going to spend her day shooting. Alia is busy filming Ayan Mukerji's action-adventure, 'Brahmastra', in Bulgaria with Ranbir Kapoor.

It's a hectic schedule so she can't afford a day off but there will definitely be a celebration on set.

Karan Johar was planning to go for Alia's birthday but he won't be able to because his mother turns 75 on Sunday and Karan is planning a big party for his mother.
