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 this week. She plans to appeal the conviction.

She killed ex-boyfriend Travis Alexander in what prosecutors said was a jealous rage because he wanted to break off their relationship.
