Belo shared on Instagram Friday night that her son, director Quark Henares, is to marry his girlfriend, singer Bianca Yuzon, whom he met three years ago.
She posted a video of Henares pulling off his planned surprise proposal for Yuzon, who thought that she was just shooting a music video.
Among those who witnessed the sweet moment was Belo's former husband, Atom Henares. The two said they're overjoyed to see their son get engaged to such a "sweet, kind, and loving girl."
Belo's current husband, Hayden Kho, and their baby daughter, Scarlet Snow, were also present.
In his Instagram Stories, Quark posted a photo of him with Yuzon thanking all those who sent them their congratulations.
Yuzon shared a heartfelt note, saying that she would love to spend the rest of her days with Quark.
"I adore you, and are so blessed that we not only get to share this unforgettable moment with you, but many more to come," Yuzon said.
The news of their engagement is the most recent reason for Belo's joy. Last year, she married Kho in a grand ceremony in Paris.
She also expressed her happiness when she attended Atom's wedding earlier this year.
