IN PICS: Bollywood celebs attend Karan Johar's birthday bash

Many B-town celebs headed towards Karan Johar's birthday bash today. Seen here are Farhan Akhtar, Sushant Singh Rajput, Malaika Arora Khan, Sanjay Dutt, Manyata Dutt, Rana Daggubati, Riteish Deshmukh, Raveena Tandon, Anil Thadani, and Tusshar Kapoor among others.

KJO, who last directed Ae Dil Hai Mushkil - which featured Aishwarya Rai Bachchan, Ranbir Kapoor and Anushka Sharma - mentioned that this birthday was all the more special to him as he is joined by his lovely twins Yash and Roohi. The much loved filmmaker became a dad recently when his twins were born via surrogacy. Since then, the new dad has been gushing over the little ones. He has also built a lovely nursery at his home for the little ones, specially designed by Gauri Khan.

The birthday boy took to Instagram to share a picture of himself and his protege Alia Bhatt and wrote, "At 45 doing my first Facebook live with a 24 year old! @aliaabhatt .."

Many B-town stars took to their social media handles to wish Karan a happy birthday. SSR wrote, "Here's wishing the most 'suitable' Rockstar of Bollywood a very very happy birthday!! Love you lots."
