AlDub was a loveteam of Maine Mendoza and Alden Richards popularized by the Kalyeserye segment of the variety show Eat Bulaga!. They were known as a "phenomenal loveteam" because of their accidental and rapid rise in popularity with the Filipino masses.
Both joining the program's cast in 2015, Alden first appeared as a guest host of numerous segments, while Mendoza originally appeared as the character 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 loveteam's main communication was through lip syncing audio clips from popular songs, films, and television shows. Their unique long-distance and nonverbal communication was a hit with the masses, which began yearning for an actual face-to-face communication between the two.
AlDub's popularity peaked in October 2015 during the Kalyeserye episode "Sa Tamang Panahon".
In mid-2018, the Alden Richards and Maine Mendoza quietly went their separate ways, opting to pursue solo projects. In 2019, Maine went public with her dating status with Kapamilya actor Arjo Atayde.
Maine, however, assured their fans that she and Alden remain "good friends and workmates" to this day.
