We first watched Sef Cadayona appear in viral commercials for a famous ice cream brand. From there, Sef joined the fifth season of "StarStruck" where we fell for his natural charms and smooth moves on the dance floor. Since joining the reality based artista search, we have seen him portray various comedic roles in Kapuso seryes such as "A1 Ko Sa'yo" and "Pepito Manaloto: Ang Unang Kuwento." Sef is also one of the main cast members of the longest-running gag shows in the Philippines, "Bubble Gang."
