Kate Major Arrest Report: What a Psycho!

Kate Major is an out-of-control mess who needs help ASAP.

That's the main takeaway from a police report filed after her arrest in Boca Raton, Fla., this weekend. If you missed it, Jon Gosselin's and Michael Lohan's ex-GF was jailed for battery after she was seen BEATING THE CRAP OUT OF A GUY AND HIS WIFE.

Police say Major allegedly had to be restrained on the ground by several people who saw her attacking and screaming at Rosario Tapia and Juan Jimenez.

The officer who wrote the report says, "I attempted to speak with [Kate Major], who was screaming and yelling obscenities at Tapia, calling her a 'fat f**k' and a 'b*tch'."

Jimenez told police he and Tapia pulled into the parking lot and noticed someone had parked in their assigned space, so they were waiting for another spot to open.

That's when Kate Major, allegedly, came bolting toward the car out of nowhere.

Jimenez claims Major opened the door and went crazy, calling him and his wife "several racial names" before attacking his wife in the hands, breast and face.

When cops tried to arrest Major, police say she resisted arrest and tried to kick the officers. After she was arrested, she continued to act belligerently.

Officials say she yelled at police and tried to make a break for it. At one point, cops say, she slapped the arresting officer and called him a "fat f**k."

She was since been released, but we have a hunch this isn't over.
