Efron, who rose to fame with High School Musical, and Gomez, who starred on the Disney Channel series Wizards of Waverley Place have never been photographed together by the press. But in 2015, Efron joined Gomez, then-rumored boyfriend Zedd and other friends for a night out in Atlanta.
Efron and Gomez have worked together, kind of; Gomez played a sorority president in the 2016 comedy sequel Neighbors 2: Sorority Rising, which saw Efron reprise his role of a fraternity president.

He then burst out laughing when main star Seth Rogen described the actress and singer as "tiny."
