"She was one of the significant individuals who helped during the war. She was also the first woman who openly wore trousers, breaking boundaries set for females.
"She was one of the first women to break the taboo of wearing a suit on camera and once, was almost arrested for wearing it in public.
"Mom named me after her to remind me that I don't have to fit in any glass slippers, there are no glass ceilings I can't break, and no boundaries I can't surpass."
Divine gave birth to Blanca on October 1, at Chong Hua Hospital in Cebu.
