America remembers her as the butter-wouldn't-melt murderess who tried to charm a courtroom with her demure demeanor. 

But nearly ten years into her prison sentence, boyfriend killer Jodi Arias has a dramatic new look - and calling. 

Arias, we're told, is 'ruling the roost' behind bars at the Perryville Correctional Facility  in Arizona. 

She has more money than other inmates, unfettered access to social media and lucrative side hustles to feed her commissary. 

She sells art online, acts as a behind-bars loan shark and even runs an ad-hoc tattoo business. 

'Whatever comes into her mind to do, she does. And no one even questions her. 

'She's got more money than anyone else, the guards all like her, and she's just on a different level from everyone else,' Berna Martez, who was imprisoned alongside the 45-year-old murderess at Perryville Correctional Facility, tells Daily Mail. 

Gone are the innocence-inducing reading glasses she donned in the courtroom. 

Now, she wears her dark hair in tight ponytails. 

Jodi Arias tried to fool America when she denied the brutal murder of her boyfriend in 2013 (seen in court)  

Travis Alexander was stabbed 27 times and shot in the head by Arias, seen together during happier times 

Arias famously murdered her on-off boyfriend, Travis Alexander in 2008 after learning that he planned to take another woman on vacation. 

The killing was ruthless. Alexander was found stabbed 27 times across his body. He'd also been shot. 

The couple had met in September 2006 at a work conference in Las Vegas. Because they lived in different states, their relationship was off-and-on for more than a year. 

But while Alexander saw the relationship as being casual, Arias took it far more seriously. 

Prosecutors claimed Arias was a jealous and manipulative girlfriend who often raged at Alexander when she found out he had been dating other women.

Authorities alleged that Alexander was planning a trip to Mexico with another woman, leading her to plot to murder him.

Alexander was found dead in his shower on June 4, 2008, after sustaining 27 stab wounds, a slit throat and a gunshot wound to the head.

A digital camera found in Alexander's washing machine also included a number of images of Arias and the victim in sexual poses, and another taken moments after Alexander was murdered.

The image showed him 'profusely bleeding' on the bathroom floor, where a bloody handprint was found that contained Arias's DNA.

Now, Daily Mail can reveal that Jodi is 'ruling the roost' behind bars. Gone is her good girl image. Now, she tattoos inmates and flirts with prison guards. Jodi is seen in a recent prison photo obtained by Daily Mail 

Former cell mates say Jodi has the run of the place. 'Everyone knows she's the one with money coming in. So she always has what she needs in the commissary' 

Arias hawks her artwork on her website, where some of the pictures have sold for as much as $2,500.

Arias initially denied the murder but later admitted to doing so as she claimed it was self-defense after he attacked her. She was convicted and sentenced to life in prison without the possibility of parole. 

Now, with all of her appeals exhausted, she's making the most of her time in prison.  

In addition to her expensive artwork, Arias sells a line of postcards and prints for $28 to $35, and she brags to the other inmates that those items sell briskly.

'Everyone knows she's the one with money coming in,' says Martez, who was released last year. So she always has what she needs in the commissary.' 

What's more, Arias has become a loan shark behind bars, buying commissary items for cash-strapped inmates — and then charging them interest when their money comes in.

'She's the top of the pecking order,' says Martez. 'Money and fame does that to a person.' 

Arias is housed at the medium security Perryville Correctional Facility

Arias also has a side hustle of tattooing her art on her fellow inmates, using a makeshift needle, pencil lead and mascara. Some inmates sport multiple tattoos created by the notorious killer.

She even tattooed her name on her ex-cellmate's ankle in 2018. 

'It was the biggest mistake I ever made,' Tracy Brown said on Investigation Discovery’s Jodi Arias: An American Murder Mystery.

'There were a couple of officers — she would flirt with or play with her hair with — and they would go in find that tattoo equipment, and they would leave it alone.'

But a male guard at Perryville tells Daily Mail that while Arias is popular in the medium security facility, she doesn't get to break the law. 

'I don't want it to sound like she is bringing contraband in, or doing something like that,' he says, 'but she understands how this place works, and she knows how to navigate around here to her advantage. She's very smart.' 

'We don't let her get away with murder,' the guard continues. 'On the contrary, she gets a lot of scrutiny.'
