The Riverdale co-stars – who play onscreen love interests Jughead Jones and Betty Cooper in the teen mystery series – split in 2020 after dating for almost three years.
After the break-up, Sprouse said uproar was expected but became but was surprised when fans moved beyond the internet to express their dismay.
“I get a lot of stuff sent to my house or my loved ones’ houses,” he told Vulture. “Death threats, really nasty, honestly criminal stuff.”
Sprouse, 31, acknowledged he and Reinhart, 26, haven’t been the only Riverdale stars to face fan uproar after a split.
“And I do think it’s because at least four of us at this table have dated our co-workers,” Sprouse continued.
“Is that just a consequence of an incredible love? Or is that what fanaticism looks like? Perhaps because those lines were blurred to our audience, it’s hard to break those things up when life moves on.”
Earlier this year Sprouse spoke about the split, admitting it was “really hard for both of us,” especially since they were still working together.
“I know we both did quite a bit of damage to each other,” he admitted on the Call Her Daddy podcast.
He had a high-profile off and on relationship with Reinhart, which, he said, was made more intense because of the Riverdale fandom.
“I think the work thing got difficult because it was hard to suspend all the way we felt about each other. And it didn’t afford us the distance to really overcome that,” he said on the podcast.
“We’re good friends now, which is awesome,” he added. “We work really well together now.”
