Luann de Lesseps, 52, was arrested in Palm Beach on charges of battery on an officer, disorderly intoxication, resisting arrest with violence and crimes against a person, Fox 29 reported.

De Lesseps, known as "The Countess" on the hit Bravo show, appeared in court early and was released on her own recognizance, according to the Palm Beach Post.

The 52-year-old slammed a door and kicked at least one police officer during the incident early Sunday, an assistant state’s attorney told the court.

"I’m going to kill you all," the state’s attorney said De Lesseps told people prior to her arrest, according to the Palm Beach Post.

Judge Ted Booras allowed de Lesseps, who has no prior offenses, to go back to New York before her next court appearance on Jan. 25.

He also advised the reality star to not to incriminate herself, and respond to him when he said she might have a drinking problem.

De Lesseps is a former wife of Count Alexandre de Lesseps, and retained the French royal title after their 2009 divorce until she married Tom D’Agostino Jr. in 2016. The two split earlier this year, according to TMZ.

Her full tweet Sunday afternoon read: "I want to offer my most sincere apologies to anyone that I might have offended with my behavior. This was my first time in Palm Beach since my wedding and being here brought up buried emotions. I am committed to a transformative and hopeful 2018."
