Aiza posted newspaper clippings and photos about the '90s youth-oriented program, TGIS.
Back then, Aiza and Anne were cast members of the second batch. They were eventually promoted to lead the third batch.
TGIS was produced by VIVA Television, and aired on GMA-7's Saturday afternoon block from August 1995 to November 1999.
Aiza wrote on her Instagram post, "#throwbackthursday: The T.G.I.S goodbye message to fans from 19 years ago... #tbt #tgis #thankgoditssabado #batang90s"
The first photo showed a newspaper advertisement about TGIS's farewell on November 20, 1999.
It also showed photos of former TGIS batch one cast members Angelu de Leon, Red Sternberg, Bobby Andrews, as well as batch two stars Antoinette Taus, Sunshine Dizon, Polo Ravales, and Dingdong Dantes.
There were also photos of Aiza and Anne with TGIS batch three co-stars Vanna Garcia, JR Trinidad, Ivan Gonzales, and Chubi del Rosario.
Anne commented on the post, "Awwwww Grabe to!!!! [heart emoji]"
Aiza replied, "Aminin kaiyak yan..."
Antoinette and Angelu also commented heart emojis on Aiza's post.
The last part of the TGIS farewell newspaper ad read, "Rest assured, VIVA will keep producing shows that will not be only similar to but even better than TGIS.
"In the year 2000, in a different time and channel... maybe, maybe..."
True enough, VIVA Television produced another youth-oriented show called H2K: Hati-Hating Kapatid, in the year 2000.
It was top-billed by Anne and Aiza, along with Rica Peralejo, Matet de Leon, Bojo Molina, and Dingdong Dantes. The show aired on IBC-13.
In June 2016, Aiza and Anne had a reunion with their TGIS batchmates. Back then, Aiza was in the Philippines for a vacation.
