Scout Willis Arrested for Underaged Drinking, Using Fake ID

The daughter of Bruce Willis and Demi Moore, Scout Willis, has been arrested for underage drinking in New York on Monday.

Not only was the second-eldest of the actors drinking, Scout also used fake identification while speaking to police near New York City's Union Square.

Scout, just one year shy of being able to drink legally, was caught drinking an 8-ounce Pakistani beer, according to New York Daily News. When an officer approached the 20-year-old, Scout flashed an ID with the name Katherine Kelly.

After further questioning, Scout finally admitted her real identity.

"The first ID isn't mine," she explained to officers, according to the criminal complaint. "My friend gave it to me. I don't know Katherine Kelly."

The Hollywood heiress was released without bail Tuesday morning after being charged with two misdemeanors- criminal impersonation and having an open container. She is due in Manhattan Criminal Court on July 31.

Scout is a student at Brown University. She has an older sister, Rumer, as well as a younger sister, Tallulah. Bruce Willis and his wife Emma welcomed Scout's half-sister, Mabel in April.

In a recent interview, 18-year-old Tallulah opened up about growing up with movie star parents. Demi Moore's youngest daughter explained her childhood as being carefree while speaking to Stylist bloggers for StyleLikeU.

"Growing up, it was our mom - she was just very much like, 'Love your body, love yourself,' whatever we wanted to do, she was very accepting," Tallulah recounted of Moore.

"Everyone should just, yeah, love and be happy, and be yourself," she added of her mother's parenting style.

Meanwhile, Moore and Willis' eldest daughter Rumer, 23, is pursuing an acting career. She appeared in last year's indie thriller film "The Ganzfied Experiment" and more recently, "Diary of Preston Plummer."
