Jodi Arias was combative on Tuesday when she was cross-examined by prosecutor Juan Martinez.

The prosecutor and the murder defendant had a series of tense moments- when Martinez asked questions she was irritated and became defensive by his style of questioning.

"Are you having problems understanding?" Martinez asked Arias during the hearing.

"Sometimes because you go in circles," replied Arias.

During their heated exchange, Arias told Martinez she had a problem with Martinez' posture when he questioned her.

"I think I'm more focused on your posture and your tone and your anger so it's hard to process the question," Arias said, according to a tweet from InSession.

Martinez reminded Arias that she lied when she was interviewed by Arizona detective Flores and he set out to prove that Arias offered a "litany of lies" when she testified last week.

Martinez presented a copy of what Arias wrote in a guest book at Alexander's memorial service. Alexander's killer wrote that he was beautiful on the inside. Martinez asked her why she thought someone who masturbated to children was beautiful on the inside.

"So you think somebody who masturbates to pictures of little boys is beautiful on in the inside, right?" he said.

"I don't think that aspect of him is beautiful at all. I think it's sickening," replied Arias.

Martinez was questioning Arias about her prior testimony when she told the jury she was uncomfortable the first time she and Alexander had oral sex.

"It felt like it was too soon," said Arias. "I acted like I liked it."

Arias also said she did not enjoy having oral sex with Alexander "internally." Martinez then played a clip of Arias' 48 Hours interview where she said sex she had with Alexander was always mutual.

Alexander, a 30-year-old Mormon motivational speaker, was found dead in his Mesa, Ariz.., home on June 4, 2008. He was stabbed 27 times with a slit from ear to ear and shot in the head. Arias confessed to the gruesome crime and said she killed her ex-lover in an act of self-defense.

If Arias is convicted of the murder that she confessed to she will likely face the death penalty and become the fourth woman in Arizona's history to die by lethal injection.
