Jodi Arias’ former cellmate claimed that she threatened the prosecutor and said she would “cut his throat” if she was found guilty but the convicted murdered is hitting back at those claims and saying they’re not true.

An Arizona jury did not believe Arias’ explanation of self-defense in the brutal slaying of Travis Alexander, and found her guilty of first degree murder following a lengthy trial where she admitted that she repeatedly lied to police, friends and family about how she stabbed Alexander 29 times, shot him in the face and slit his throat.

Despite being locked up in the Estrella jail in Maricopa County, Jodi communicates via Twitter with the outside world and recently wrote that Cassandra Collins lied during her interview with Troy Hayden at FOX 10.

“Really, @troyhaydenfox10 ??? A woman who was found by the court to be incompetent to stand trial?” Arias wrote to the reporter.

Collins claimed that Arias was threatening Juan Martinez prior to her first-degree murder conviction.

"She said that if she was given the death sentence … she wanted to get her revenge... she knows inmates on the outs to do a mafia bow tie.. yeah. Cut his throat," Collins said in the interview.

However, Arias took offense to the quotes and hit back against Collins, writing: “You conveniently failed to mention that -- way to mislead your viewers.”

Hayden asked her if she was denying that she said those things she responded “Of course.”
