Kathryn Bernardo caught many by surprise, including Daniel Padilla himself, when she called her onscreen partner her "mister" in an Instagram post.
In an episode of "Tonight with Boy Abunda" on Friday, the actress shared the story behind her sweet caption.
"Kapag wala kasi akong magawa, mahilig ako tumingin ng pictures. Tapos naalala ko na ang dami naming magagandang pictures na hindi ko pino-post," she admitted. "Kasi gusto ko private iyong mga iba."
"And then noong guesting sa 'Family Feud,' [tinawag niya akong] 'Misis ko,' so parang cute iyon. Sabi ako, 'Ano na caption ko?' Simple lang, eh hindi 'Mister ko.'" she added.
Bernardo said their characters in their newest film "Can't Help Falling In Love" also call each other "mister" and "misis".
The Star Cinema flick, which saw them play a married couple, has made more than P100 million in just four days. It is still showing in more than 400 cinemas.
Asked for his reaction, Padilla said: "Nabigla ako kasi ako lang iyong nagpo-post ng mga ganoon eh. Siyempe nakakatuwa naman dahil galing kay Kathryn mismo."
