Karan Johar’s Big Birthday Bash – Alia Bhatt went live on Facebook just before the big party of Karan Johar and the video was captioned, “Karan Johar’s Birthday Unplugged ft. Alia Bhatt. For the first time ever, presenting #KaranJohar ft. #AliaBhatt LIVE! The celebration begins!” was a testimony to the close bond the actor-director share. While Bollywood celebrities showed up for the birthday bash in huge numbers, it was a very special one for Karan since he welcomed his little ones Yash and Roohi this year. They were the little cherries on his birthday cake!
