DigiTour is a traveling event that features YouTube, Vine, Twitter, and Instagram stars. Greg was supposedly asked to tour with DigiTour 2013.
An ex-friend of Lainey's revealed information about Greg and Lainey's early relationship. (Source) The friend also leaked their Skype conversations with Lainey to back up what they were saying. In 2015, Lainey confirmed these screen shots were real in a YouNow live show.
The friend said Lainey talked about how they planned on switching to online college because Greg was asked to join DigiTour 2013. In the chat logs, Lainey says they wanted to travel with him around the country and not ruin his opportunity. (Source)
Virtually no information is available about this supposed touring gig, as Greg never seemed to be apart of DigiTour.
