Back in the days when Vine was still thriving and more popular content creators were discovered on the app, David and Alex quickly became friends through their shared popularity on the six-second video platform. Both were known for their comedy sketches on the app, which is how they also met other Vlog Squad members like Zane Hijazi, Liza Koshy, and Jason Nash. 

From there, they moved to LA together and became roommates. 

"Alex and I moved out here four years ago together," David said in his video where he gifts Alex a Tesla. "He DMed me and he was like 'Let's move out! Let's f-----g do it!'"
