A pair of Michigan sisters, including one nine months pregnant, allegedly stabbed and threw hot oil at a restaurant worker during a dispute over a wrong food order, according to reports.

Brianna and Kierianna Long were hit with a slew of charges, including assault with intent to murder, for the shocking beatdown that unfolded on May 30 at a Detroit chicken restaurant, ClickonDetroit reported.

After the sisters received the wrong food order from the 23-year-old worker, they began arguing with her and hopped behind the counter, prosecutors said, according to the outlet.

The twisted siblings then threw items at the employee, hit her with pots and pans, and tried to throw hot grease at her head, Metro Detroit News reported.

As the worker tried to throw things back at Brianna, 29, and Kierianna, 26, the sisters picked up a knife thrown at them and stabbed the staffer in the stomach, authorities alleged.

One of the sisters even proclaimed, “I’m going to kill you,” during the vile assault.

The worker was taken to a local hospital, where she underwent surgery, as the Long siblings attempted to drive away from the scene. Brianna and Kierianna were eventually taken into custody.

Brianna, who was 9 months pregnant, gave birth four days before her arraignment in connection with the stabbing, ClickonDetroit reported.

Her defense attorney claimed the worker sparked the assault by stating that she didn’t “give a f–k” about the food order mixup and started throwing things at the sisters first.

The new mother pleaded with the judge, stating that she was innocent and had a 4-day-old baby at home, the outlet reported.

The judge, however, ordered Brianna held on a $25,000 cash bond and Kierianna on a $100,000 cash bond after they pleaded not guilty to charges.
