text: Jodi Arias has reported to prison to begin serving her life sentence for murder, and she has a new mugshot. The image shows a stone-faced Arias dressed in an orange prison uniform. It's a sharp contrast from her original booking photo in which displayed a smirk. She later said she flashed the grin because that's what her victim would have done if he were in the same situation. She also figured the mugshot would be all over the Internet, 'so why not?' Arias was convicted of murder and sentenced to life in prison - with no change of parole - on Monday. She plans to appeal the conviction. Scroll down for video . Life in prison is no laughing matter: Jodi Arias looks serious in a new mugshot (left) taken  this week, as she starts her life in prison sentence for murdering ex-boyfriend Travis Alexander. In her first mugshot, taken in 2008 (right), Arias smiled on purpose because she knew the picture would be widely published . She killed ex-boyfriend Travis Alexander in what prosecutors said was a jealous rage because he wanted to break off their relationship. Arias killed her ex-boyfriend in 2008 after a stormy relationship. Prosecutors say she murdered him in a jealous rage because he wanted to break off the relationship. She shot Alexander and stabbed him nearly 30 times in his suburban Phoenix home before fleeing and driving to Utah to meet up with another romantic interest. She was arrested weeks later and initially denied any involvement. International media attention soon followed after she did two television interviews in which she told a bizarre story of masked intruders breaking into the home and killing Alexander while she cowered in fear. She subsequently changed her story and said it was self-defense after Alexander attacked her on the day he died. The rest of her life: On Monday, a judge sentenced Arias to life in prison without the possibility of parole.

Victorious for some: Chris Hughes, friend of victim Travis Alexander, claps his hands as he leaves the Maricopa Count courthouse following sentencing on Monday . Victim: Prosecutors said Arias heartlessly killed Alexander (pictured together above) because he wanted to break up with her . Her 2013 trial became a media circus as details of their kinky relationship and the violent crime scene emerged in court and were broadcast live. Spectators traveled to Phoenix and lined up in the middle of the night to get a seat in the courtroom to catch a glimpse of what had become to many a real-life soap opera. Interest in the case intensified after Arias did a jailhouse interview minutes after she was convicted of murder, telling a local TV reporter that she preferred the death penalty over life in prison. 'I would much rather die sooner than later. Longevity runs in my family, and I don't want to spend the rest of my natural life in one place,' she said. The original jury was deadlocked on whether to sentence her to death, setting up another penalty phase trial that began last year. After months of testimony and efforts by Arias' lawyers to portray Alexander as a sexual deviant who physically and emotionally abused her, the second jury also failed to reach a unanimous decision — this time 11-1 in favor of death. The 11 jurors who wanted the death penalty said the holdout juror had an agenda and was sympathetic to Arias.
