Sidharth Malhotra was spotted in his car and Karan Johar, who tweeted to Alia yesterday that his newborn twins are waiting to see their 'sibling,' took charge at the entrance:

The guest-list also included Ayan Mukerji, who is directing Alia and Ranbir Kapoor in his next film, and Puneet Malhotra:

Varun Dhawan would certainly have been there, had he not flown out to Bangkok with rumoured girlfriend Natasha Dalal on a working holiday.
Alia Bhatt was wished by many other colleagues on Twitter - her Highway co-Randeep Hooda; Shandaar and Udta Punjab co-star Shahid Kapoor; actors Sushant Singh Rajput, Dia Mirza and Jacqueline Fernandez; designer Prabal Gurung, whose clothes she often wears; and, notably, Hollywood director Paul Feig who described her as a 'huge talent' and said he'd like to work with her.

Alia Bhatt, daughter of Mahesh Bhatt and Soni Razdan, debuted in 2012's Student Of The Year and in just four-going-on-five years has racked up an impressive body of work and a reputation as a major talent. She's currently sweeping awards season with her performance in last year's drug drama, Udta Punjab. Apart from the film with Ranbir, Alia will also star in Zoya Akhtar's Gully Boy with Ranveer Singh.
