Antonella Barba appears in a mugshot taken after she was arrested on suspicion of being involved in an eight-person drug ring

American Idol star Antonella Barba is blaming the talent show for her life's downward spiral from aspiring singer to a convicted criminal, as she faces a decade behind bars.

The singer, 32, appeared on the singing competition in 2007, where she sang her way into the Top 16, before being eliminated and going on to pursue a career in music in acting.

Twelve years on it appears as if her dreams of making it big are all but over, after the singer, back in August, pleaded guilty to possessing and distributing fentanyl.

Newly filed court documents, ahead of her sentencing tomorrow, point to the talent show's 'detrimental' impact on her life as a major factor in her downward spiral.

The disgraced star caused some controversy during her time on the show in 2007 after racy pictures of her appeared online. In the latest news the former American Idol contestant has pleaded guilty to possessing and distributing fentanyl

The documents shared with celeb news outlet, The Blast, illustrated how the singer saw herself to be a 'resilient, deeply religious, selfless and driven person...someone who could rightfully be called a perfectionist.'

The court papers also revealed how Barba's mother watched her daughter's life change, for the worse, after taking part in the talent show in 2007.

'One of the common themes is that the American Idol experience brought about a detrimental change in Ms. Barba's life,' it reads.

'Ms. Barba's mother believes when American Idol happened and "the world intruded and interrupted her . . . dream of a career in architecture" that this is "where it all went wrong".

'Ms. Barba's sudden move to Hollywood following American Idol 'was a recipe for disaster' and when it came to pass that Ms. Barba was unable to 'achieve the results she wanted, it was devastating to her.'

Antonella Barba was just 19 when she appeared on the show. She made it to the Top 16 before being eliminated and going on to forge a career in music and acting

The aspiring singer, who was only 19 at the time, had already caused some controversy during her time on American Idol in 2007.

She was photographed posing in a wet t-shirt on the fountain of a World War Two Memorial in Washington DC and for other racy photographs of the singer that were leaked on line.

In the years since American Idol while Barba has remained in the entertainment industry, she has never quite made it big time, having made a few music albums, acted minor roles in a couple of films and appeared in the 2012 season of Fear Factor.

Her first brush with the law came in 2011, when she was arrested for shop-lifting in New York City and ordered to do community service.

Her latest arrest, in late 2018, came after she was found with a package of drugs in her car.

Prosecutors later accused her of being a courier for a drug ring, one of eight members of the ring operating out of Hampton Roads, Virginia, North Carolina from late 2017 to early 2018.

Barba reached a plea deal with prosecutors earlier this year. However, in the new court documents Barba's lawyer has asked for a shorter prison sentence than the expected ten years the singer faces.

The lawyer said the former American Idol contestant had been kept in the dark about the drug ring and had little insight into her actions.

New court documents showed to the blast have blamed the singer's appearance on the show for bringing a 'detrimental change' to the young woman's life. Not having achieved her dreams, the documents say she was 'devastated' and that this contributed to her fall from grace

In bidding for a lower sentence, the lawyer argues the singer was only a minor part of the operation.

'The extent of Ms. Barba's involvement in this case is limited to delivering one shipment of drugs and that single instance forms the sum total of her relevant conduct.'

The lawyer goes on to say the former American Idol contestant had little knowldge of the drug ring's operations or into the contents of the package she was delivering.

'Ms. Barba also did not participate in any of the planning or organization nor did she exercise any decision making authority.

'Ms. Barba was told where to go, when to go, and what to do when she got there. She did not break down the contents of the package into smaller amounts for resale and she did not collect any proceeds. She had no pecuniary interest in the package and did not stand to benefit in any way by the sale of the narcotics. Ms. Barba was paid only to deliver the package.'
