June 3 (UPI) -- Riverdale star Lili Reinhart is publicly coming out as bisexual for the first time.
The 23-year-old actress posted about her sexuality Wednesday on Instagram Stories while promoting a Black Lives Matter protest.
"Although I've never announced it publicly before, I am a proud bisexual woman. And I will be joining this protest today. Come join," she wrote.
Reinhart shared the news alongside a poster for an LGBTQ-led Black Lives Matter protest in West Hollywood.
"I tolerate a lot of rumors and slanders from people online claiming to be my fans," the actor said on Instagram Stories. "But attacking my friends, baseless accusations, leaking my address and sending them death threats are all qualities of insanity and fanaticism."
Sprouse said he expected public scrutiny of his relationship but won't tolerate recent behavior from fans.
"When I first stepped into a public relationship this was one of the foreseeable consequences. And while I truly never intended 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," he said.
Reinhart and Sprouse play Betty Cooper and Jughead Jones on Riverdale. Series creator Roberto Aguirre-Sacasa confirmed in May that the CW series will have a significant time jump in Season 5.
