Demi Moore's daughter is in trouble. Scout Willis, 20, was arrested for allegedly drinking a beer and handing cops a fake ID in New York City's Union Square subway station Monday night in New York City.

According to WABC, when Willis was stopped by police at around 6:50 p.m., she gave officers a New York State ID with the name Katherine Kelly. After further questioning, she gave them her real California ID with the name Scout Willis.

According to the criminal complaint, she told police, "My name is Scout Willis. The first ID isn't mine. My friend gave it to me. I don't know Katherine Kelly."   People magazine reported that she was charged with two misdemeanors.

Willis was released without bail Tuesday morning; she'll return to Manhattan Criminal Court on July 31. Willis, the second daughter of Moore and Bruce Willis, is a student at Brown University.
