Amber Portwood's May 24 Mugshot: Is She at Peace With Going to Prison?

Amber Portwood's newest mugshot may be her most revealing yet.

Amber, who decided yesterday to give up on rehab and told a judge to enact her five-year prison sentence, looks almost at peace in this mugshot. Compare that to her most recent mugshot, where she seemed half-asleep, or the one from this past December, where she looks unhappy.

As her brother, Shawn Portwood, told E! Online, "Amber finally had enough. The system failed her, and that is all I can say."

"I really feel for my sister," he continued.

"She does not deserve to be there or anything that has happened to her. She is there because of who she is."
