AlDub is a Philippine supercouple which first appeared in the Kalyeserye portion of the "Juan for All, All for Juan" segment of the variety show Eat Bulaga! They were also called as the "phenomenal love team" due to their rise in popularity after they were accidentally paired on the July 16, 2015 episode of the Problem Solving portion of "Juan for All, All for Juan" which later became the first episode of Kalyeserye. AlDub was derived from a portmanteau of the tandem's character names in Kalyeserye, namely Filipino actor Alden Richards, who portrays a fictionalized version of himself, and Yaya Dub (Divina Ursula Bokbokova Smash, a playful reverse-acronym of Dubsmash), portrayed by Dubsmash Queen personality and socialite actress Maine Mendoza, who initially does not talk and interacts through lip-syncing. which is now scandal on relationship.
Both joining the program's cast in 2015, Richards first appeared as a host of Eat Bulaga! segments, such as the "That's My Bae" portion; while Mendoza originally appeared as Yaya Dub in the show's portion "Problem Solving". During the first few months of Kalyeserye, they exclusively interacted through the show's split screen frame, the AlDub couple's main communication is through lip syncing audio clips from popular songs, films and TV series. After they personally met in September 2015 and Yaya Dub was later allowed to speak, the couple's interaction is no longer limited to split screen and lip-syncing.
