Convicted boyfriend killer Jodi Arias asked a judge Wednesday to delay her upcoming death penalty trial and promised to reverse her decision to represent herself if she's allowed to fire her lead attorney.

Last week, Arias was granted permission to represent herself at the second phase of her murder trial, which is scheduled to begin on Sept. 8.

Although Maricopa County Superior Court Judge Sherry Stephens advised Arias not to drop her lawyers, she granted her request and appointed her lead attorney, Kirk Nurmi, and his second-chair attorney, Jennifer Willmott, as her legal advisers.

Days later, Nurmi filed a motion asking the judge to let him resign from the case due to his ongoing tension with his client.

On Wednesday, the 34-year-old former waitress appeared in court for the first time representing herself to ask the judge to postpone her sentencing trial, claiming that she has had difficulty interviewing one of her expert witnesses while locked in jail, reports USA Today.

However, prosecutors objected to the motion, arguing that the trial has already been delayed long enough and that Arias must adhere to the timetable she agreed to when she successfully sought to represent herself, reports NBC News.

Judge Stephens set a hearing to consider the motion to delay the trial for Aug. 22, Reuters reports.

Arias also told the court that she will cease to represent herself if Kirk Nurmi is removed from the case.

Likewise, "Nurmi reiterated his desire to withdraw from the case, citing his original attempt to withdraw in 2011 and Arias' repeated attempts to have him fired," reports USA Today. A decision has not been announced.

Back in May 2013, Arias was found guilty of the first-degree murder of her lover Travis Alexander, who was murdered in his Phoenix home in in 2008. According to medical examiners, Arias stabbed him 27 times, primarily in the back, torso and heart. She also slit Alexander's throat from ear to ear, nearly decapitating him, and shot him in the face before she dragged his bloodied corpse to the shower.

Although Arias was convicted of murder, the jurors failed to reach a unanimous decision on her sentencing. As a result, her retrial will begin next month to determine whether or not she should be sentenced to death, life in prison or life with a chance of release after serving 25 years, Reuters reported.
