Sarah Geronimo looked giddy with excitement as she fangirled over Regine Velasquez while rehearsing for a duet.
The young ABS-CBN singer and GMA-7 artist performed "Sana Maulit Muli" in a one-minute video that has become viral.
Joever Hamoy Banquisio posted the video on Facebook on August 8 and to date, it has reached over 629,000 views.
At one point, Sarah faces the camera and flashes the victory sign and composer-arranger Louie Ocampo playfully makes an appearance in the background.
The video could have been shot while the two singers were rehearsing for R3.0, Regine's October 2017 anniversary concert.
Sarah has been vocal in saying that Regine is her idol. The Popstar Princess got her big break in showbiz in 2003 when she won the singing contest Star for A Night, which Regine hosted.
