'Jodi Arias: Dirty Little Secret' Sneak Peek: 'You're Acting Crazy' (Video)

Lifetime on Wednesday gave a sneak peek at its upcoming original movie Jodi Arias: Dirty Little Secret.

The movie, based on the real-life murder trial, stars Tania Raymonde (Lost) as Jodi Arias, a seductive 28-year-old aspiring photographer recently found guilty of killing her former lover Travis Alexander (Jesse Lee Soffer, The Mob Doctor), who was found nude in his apartment shower with a slit throat, 27 additional stab wounds and a bullet to the head.

While investigating the violent killing, police in Mesa, Ariz., retrieved a digital camera from Alexander's washing machine, revealing shocking images authorities claim Arias took of their sexual escapades, as well as during and after his murder.

While Arias plead not guilty and said she killed Alexander in self-defense, police concluded that when Alexander broke off his relationship with Arias, she became a real-life "Alex Forrest" (the character portrayed by Glenn Close in Fatal Attraction). They say Arias stalked her ex-boyfriend, whom she successfully seduced one final time before murdering him, and then tried to cover up the murder.

This clip from the movie shows Travis breaking up with Jodi -- and her not taking it very well.

When she questions why he's getting a text from another woman, he tells her, "This is crazy. You're acting crazy. This is like insane jealousy."

She replies, "I feel like a prostitute, Travis. A piece of toilet paper."

He later tells an incredulous Jodi that she's taking things too fast and that they need to take a break.

"I think that we need to take some time and rethink things," he adds. "It's way too much."

Jodi Arias: Dirty Little Secret debuts at 8 p.m. Saturday, June 22, on Lifetime. Watch the clip above.
