ABS-CBN’s “Bida Kapamilya” offered a free watching party of “It’s Showtime” grand debut on GMA this Saturday at the Ynares Center in Antipolo.

The event, which commemorates the noontime show’s historic airing on its former rival network, was anticipated by fans.

Those who went to the watch party shared that they were most looking forward to witnessing performances of “It’s Showtime” hosts, especially Vice Ganda who unleashed an “unkabogable” birthday performance.
