PICS: Aamir Khan, Alia Bhatt and Imtiaz Ali arrive at Ranbir Kapoor's birthday bash

Ranbir Kapoor is ringing in his 35th birthday today in style, amidst friends and family. The actor, who usually likes to keep his birthday celebrations low key, decided to throw a big bash this year. Seen here are Aamir Khan and Alia Bhatt, heading towards Ranbir's bash. 

Aamir, who is sporting his Thugs of Hindostan look these days, smiled for the paps. Alia Bhatt looked pretty in a red shirt and she drove in to the venue. Also seen is Ranbir's favorite director Imtiaz Ali. 

Ranbir and Alia will be seen together in the Ayan Mukerji movie Dragon. Ranbir will also be seen in the Sanjay Dutt biopic where he has essayed the junior Dutt to perfection. He was last seen in the movie Jagga jasoos opposite Katrina Kaif. The movie, which was produced by Kapoor himself, did not fare well at the box office.

The who's who of B-town is expected to make their presence felt at Ranbir's bash tonight. Stay tuned for more updates.
