Cole Sprouse and Lili Reinhart spoke out after they and other castmates from the CW show “Riverdale” were accused of sexual assault or harassment from anonymous Twitter accounts on Sunday; allegations they deny.

On Sunday, Sprouse, 27, addressed the allegations, stating on Twitter: "Earlier today myself and three other cast mates were falsely accused of sexual offense by anonymous accounts on twitter. I take these accusations very seriously, and will be working with the right teams to get to the root of it."

The “Suite Life of Zack & Cody” actor continued: "False accusations do tremendous damage to victims of actual assault. Furthermore, I would never seek to silence anybody. I encourage that people look into the accusations themselves, as the events detailed were factually untrue."

“This seems to be the latest claim in a series of incidents seeking to baselessly cancel my cast mates and me,” Sprouse ended his message.

Reinhart, 23, retweeted Sprouse’s tweets and added: “I have always taken sexual assault allegations seriously. But it was proven that this account was created specifically to create false stories about me and my cast.”

She continued: “I can’t think of something more twisted than lying about sexual assault. It invalidates the men and women who are brave enough to come forward with the truth. This kind of lie can ruin lives and careers and I can call it a lie because the person who made the allegations already admitted that the stories were fabricated.”

Reinhart also said they are "looking into taking legal action" and called the claims “triggering” and harmful for survivors of sexual assault. “I hope and pray that this does not discourage real survivors from speaking out about their experiences," she concluded.

Morgan retweeted Sprouse’s thread but has not yet publicly commented. Apa has not made any comments about the accusations either.

“Riverdale” castmate Madelaine Petsch also spoke out about the claims against her co-stars, stating on her Instagram Story (via E!

She also tweeted: “As someone who has been sexually assaulted, I am deeply deeply disturbed that anyone thinks that it is okay to falsely accuse someone of sexual assault. This is why real assault allegations can sometimes not be taken seriously, you should be ashamed. This is disgusting."
