A former Playboy model was arrested after she went on an expletive tirade and slapped a fellow passenger aboard a Delta flight

Ex-‘Baywatch’ Actress Patricia Cornwall was arrested by the FBI after she went on an expletive-laced tirade and slapped a fellow passenger aboard a Delta flight from Tampa to Atlanta.

The unhinged woman — identified as Patricia Cornwall — was arrested by the feds after the wild incident aboard Flight 2790 on Thursday, Atlanta police said in a statement.

She was accused of causing a midair “disturbance” that led to the “injury of fellow passengers and Delta employees,” police said.

A video tweeted by ATL Uncensored shows the woman standing in the aisle cursing at a male passenger as they exchange heated words.

• “Put your f— mask on!” she yells, as her own mask sits below her chin.
• “Sit down, Karen!” he shoots back at the woman.
• “Mask up!” she shouts.
• “You mask up, b—!” he yells back.
• She is then seen slapping the man, who shouts, “You’re going to jail!”

Crew members are seen trying to restrain the woman, who is led down the aisle while yelling, “You f— piece of s—!”

Someone in the clip said the woman “went crazy on the airplane, punched this man in the face, spit on him, scratched him (and) poured hot water on my leg.”

When the flight landed at Hartsfield-Jackson Atlanta International Airport at 6:10 p.m., police met with airline employees at Gate A11, where passengers described the incident.

“Flight 2790 from Tampa to Atlanta was met by law enforcement after an unruly customer disturbance during flight,” a Delta rep wrote in an email.
