Jenna Jameson seems to be heading in a downward spiral lately, most recently being accused of assaulting her assistant with iPhone brass knuckles over the weekend.

Jameson is arguably the most famous name in porn, but after retiring from the XXX business in 2008, she can’t seem to stay out of trouble.

The former porn star supposedly beat up her assistant Britney Markham in California over the weekend. Brass knuckles are illegal in the state, but Jameson managed to turn her iPhone accessory into an assault weapon after she accused Markham of stealing from her, TMZ reported.

According to the victim, the “Queen of Porn” began yelling at her when they entered a Newport Beach salon on Saturday hours before Jameson planned to celebrate her 39th birthday Heat Ultra Lounge in Anaheim that night.

That’s when she supposedly turned her faux brass knuckle iPhone case into a wepon and began beating down on Markham while yelling, “I’ll f--king kill you!” TMZ said.

Picture’s from her assistant’s Twitter account showed the supposed victim also had a brass knuckle iPhone case, but no reports said Markham used her device against Jameson for self-defense.

Markham was hospitalized for her injuries, but that didn’t stop her from engaging in a Twitter feud with her boss.

Both of the ladies later deleted their tweets about the fight, but the Daily Mail quoted Jameson before she took down the post Sunday night.

She said: “Wow just got robbed by a friend @britneymarkham she accused me of gusting her and then broke into my home and took everything.”

The Bert Show reported that Markham retaliated by posting a video of herself in the hospital with the caption: “This is what you did to me and u accuse me of stealing.” Her video has been removed as well.

She has since filed a restraining order against Jameson, according to court documents obtained by TMZ, who was released from custody on Sunday night.

Since 2006, Jameson has been in a relationship with mixed martial arts fighter Tito Ortiz, who is the father of her 4-year-old twin boys.

Ortiz was arrested and charged with felony abuse against Jameson in 2010 after the pair had a heated argument. He accused her of being addicted to pain pills and said she had been acting erratically, but later recanted his story.

Last May, Jameson was arrested for drunk driving when she crashed her car into a light pole and sustained minor injuries.

The porn star didn’t have a reputation for illegal activity while she was a performer in the adult film industry, but she has been struggling personally ever since then.
