Stars including Salman Khan, Alia Bhatt, Kriti Sanon, Shahid Kapoor made sure that the show went on even as some fans chose to leave the MetLife stadium due to the downpour.
But there were thousands of fans who braved the bone- chilling cold just to catch a glimpse of their favourite stars at the event.
Salman took to Twitter and shared, "It's raining in #NewYork, loving the weather. If it does rain tomorrow it will be awesome dancing in the rain at #IIFA."
Filmmaker Karan Johar, Saif Ali Khan, Varun Dhawan, Anupam Kher, Diljit Dosanjh, Kamal Khan and Riteish Deshmukh were also in attendance at the event which saw a special performance by music maestro A R Rahman.

The Oscar-winning musician collaborated with Diljit Dosanjh, Javed Ali, Jonita Gandhi, Benny Dayal, Neeti Mohan and Haricharan Seshadri for a music medley.
Due to the rains, some concert attendees were not able to make the most of the event.
"I am disappointed as we couldn't enjoy the concert. We walked almost for an hour as we were not getting any cab. We had just bought tickets for 50 dollars each for today's show. We are not sure if we should come tomorrow," Shaheen Bhatt, who is the sister of Alia, told PTI.
"We had paid 50 dollars for the tickets. We wanted to see the show, so we had booked front row tickets but the rains forced us to move behind. For tomorrow we have booked two tickets for 1000 dollars," she said.
The event was hosted by Riteish Deshmukh and Maniesh Paul.
