Cole Sprouse says he's endured 'baseless accusations' and 'death threats'

Cole Sprouse has opened up about the incessant abuse he's copped online.

The Riverdale actor, 27, took to his Instagram Stories to hit back at those "claiming to be my fans" who have subjected him to slander and spun rumours.

"I tolerate a lot of rumours and slander from people online claiming to be my fans," he wrote on April 20.

"Fans who feel entitled to my privacy precisely because I never indulged them. But attacking my friends, baseless accusations, leaking my address, and sending death threats are all qualities of insanity and fanaticism. Choose humanity stop being [a clown].'"

Sprouse seemingly referenced his relationship with on-screen and off-screen girlfriend Lili Reinhart and his choice to keep their romance private.

"When I first stepped into a public relationship this was one of the foreseeable consequences," he said.

"And while I never truly intend to indulge any part of my private life to the ravenous horde, it's clear my restraint in updating them has allowed them to push their own agenda onto my habits and lifestyle."

The actor has been in a relationship with Reinhart since they met on the set of Riverdale in 2016.

Sprouse and the rest of the Riverdale cast remain in lockdown as production has been halted amid the coronavirus pandemic.

Warner Bros. TV pulled the plug on the program after a member of the production came into close contact with someone who'd tested positive for the virus.

The studio issued a statement saying: "We are working closely with the appropriate authorities and health agencies in Vancouver to identify and contact all individuals who may have come into direct contact with our team member. The health and safety of our employees, casts and crews is always our top priority."
