In a recent interview with ET Canada, Shawn admitted that they've definitely discussed it. "It's 100% going to happen," Shawn said. "Niall and I talk about this pretty much every time we see each other."
Last month, Shawn posted an Instagram of the pair hanging out which sparked A LOT of buzz among fans.
"We started really seriously talking about it that night," he said.
"The truth is that we're just really really good friends and we always really enjoy just hanging out and sometimes you don't get a lot of time to just hang out so that's what we want to do, but we'll get it."
