BOSTON -- A 20-year-old heiress was arrested Saturday morning after police said she left the South Street Diner without paying and got behind the wheel of her car while drunk.

Jacqueline Kent Cooke, daughter of late Washington Redskins owner and billionaire Jack Kent Cooke, pleaded not guilty to charges of operating under the influence.

Police said an officer followed Cooke and her friend after they left the restaurant without paying around 5:15 a.m.

The police report said the officer saw Cooke’s keys to her BMW 325i fall out of her purse when she went back inside the restaurant to pay the bill, though she denied the car was hers.

The officer advised her to take a cab home, police said.

Police said Cooke pulled up her skirt to moon the officer, and then gave him the middle finger, before eventually getting into the BMW and starting the engine.

The officer stood in front of the car and called for backup, police said.

“He was trying to protect her from herself,” Suffolk District Attorney Daniel F. Conley told the Boston Herald.

Police said Cooke then asked the officer, “Do you know who I am?” and told the officer that “$1 billion goes a long way” and that he would lose his badge, according to the police report.

“I guess Cooke is the most recent example of individuals who think themselves pretty important,” Conley told the Herald. “If you have to ask that question rhetorically, you’re probably not going to win yourself many friends in the law enforcement community.”

Cooke was released on personal recognizance.

Jack Kent Cooke died in 1997.

He left his daughter with a $5 million trust, but she reportedly sued his estate for $275 million last year, the Herald reported.
