According to federal court documents, Petty will plea guilty to one charge of "failure to register" with the state of California, and prosecution will seek a lighter sentence.
The mandatory minimum charge, according to TMZ, is "5 years of supervised release" with the maximum set at a staggering "10 years in prison with a lifetime of supervised release".
The 43-year-old's criminal history goes back to his teen years. He was convicted of first degree attempted rape back in 1995, but despite considerable amounts of public criticism, the "Pound The Alarm" singer has frequently rushed to her husband's defense.
She seemingly called the conviction into question in a snarky post on social media, saying "He was 15, she was 16. In a relationship [...] But go awf Internet. Y'all can't run my life. Y'all can't even run y'all own life. Thank you boo."
In unrelated charges, Petty has also been previously convicted of first degree manslaughter, and he served a 7 year prison sentence for his part in the fatal shooting that occurred in 2002. He was later released in 2013.
"I do want to get into something. Who thinks it’s good that Meghan Markle left the UK with her husband? … Kudos to Harry. This is what I love about my husband," she said, referring to Petty. "Real men always say ‘a happy wife a happy life.’ That’s what real men say. That’s so attractive. It turns me on. Put your woman first."
Petty and Minaj recently welcomed their first child, but due to his status as a sex offender, he was required to get permission from a court in order to be at the hospital for his birth.
