In an article, it read:
"Twenty One Pilots' world takeover is inevitable. Not only did their last full-length album, Blurryface, debut at No. 1 on the Billboard 200, the band just continues to gain fans from all walks of life, daily. (It probably doesn't hurt that drummer Josh Dun is currently dating Halsey either!)"
Neither Dun nor Halsey have confirmed this to be true.
It was rumored that Frangipane filmed the two on a date.
