The daughter of Walmart founder Sam Walton spent the final hours of her birthday in jail Friday night after being arrested for drunk driving.

Texas Highway Patrol Senior Trooper Gary Rozzell told The Weatherford Democrat that Trooper Jeff Davis stopped Alice Walton on Interstate 20 in a construction zone for a traffic violation.

"Through an investigation at the scene, [Walton] was determined to be intoxicated during a field sobriety test," Rozzell explained. "We're going to treat this like anybody else."

The heiress declined to submit to a breathalyzer and was arrested for first offense driving while intoxicated. She was taken to the Parker County Jail, where she spent the next nine hours behind bars before being released on $1,000 bond at around 8:40 a.m. ET.

The paper noted that Walton's mug shot had been omitted from the Parker County Jail website until the Parker County Sheriff’s Office was contacted.

"There's no conspiracy," Parker County Sheriff Larry Fowler said.

A spokesman for the family said that Walton took "full responsibility" for her actions.

"Ms. Walton was pulled over by a patrolman with the Department of Public Safety for driving 71 mph in an unattended 55 mph construction zone," a statement read. "She was returning home from a birthday dinner with friends at a Fort Worth restaurant. She accepts full responsibility for this unfortunate incident and deeply regrets it."

Although the Texas Highway Patrol charged her with a first offense, records from the Springdale District Court in Arkansas indicate that she was also convicted of driving under the influence in 1998.

According to UK's The Independent, she had hit a gas meter and tried to intimidate the arresting officer in that case.

"I'm Alice Walton, bitch!" the billionaire allegedly screamed.

She later blew a 0.16 blood-alcohol level at the hospital. The case was settled with a $925 fine.

In another incident, no charges were filed after Walton killed a 50-year-old mother of two with her Porsche. It's not clear if alcohol was a factor in that case.

Forbes lists Walton as the ninth richest person in the U.S. and the third richest woman in the world. She has an estimated wealth of $21 billion.
