The fourth edition of the annual event will see live performances ranging from music, to comedy, dance and fashion.
The event will see Indian YouTube celebrities along with several others with a global reach.
While famous Indian faces like AIB, Kenny Sebastian, Zakir Khan and Vidya Vox among others will be there, several video-makers from across the globe like Caspar Lee, Mike Tompkins, Kurt Hugo Schneider, Tanner Patrick and Sam Tsui will also attend the event.
David Powell of YouTube Asia Pacific said that the Mumbai chapter of the FanFest has "become a marquee event" for the company.
"YouTube FanFest has truly become our marquee event to celebrate YouTube creators from India and around the world. We're excited to see (and hear) the excitement that YouTube creators drum up among thousands of fans," Powell said.
"With some of the most exciting local and international talent performing side by side for some of the world's craziest fans it's no surprise that Mumbai is one of the biggest stops on the global YouTube FanFest calendar and we're thrilled to be coming back for our fourth year," Jasper Donat of Branded said.
Casper Lee, who has a fan following of 6.5 million users on YouTube, said that he is "beyond excited" and wishes to find out if he had "any friends in Bollywood".
"This will be my first time taking part in the YouTube FanFest in India and I'm beyond excited. If the energy is the same as the other FanFests, it's going to be an amazing evening — and oh I am also excited to find out if I have any friends in Bollywood," Lee said.
