Scout Willis has been busted for underage drinking and using a fake ID!

The 20-year-old daughter of Demi Moore and Bruce Willis was arrested Monday night in Union Square New York, reported the NY Daily News.

According to cops Scout produced a fake ID after being caught drinking a beer. She later confessed to her real name and claimed her friend gave her the ID.

“My name is Scout Willis,” she told the officer, according to the criminal complaint. “The first ID isn’t mine. My friend gave it to me. I don’t know Katherine Kelly.”  

Scout was booked for two misdemeanors -- criminal impersonation and open container — and has since been released without bail. She is ordered to return to Manhattan Criminal Court on July 31. 

As Breaking Celebrity News previously reported, she's not the first Willis sister to land in hot water with the cops for drinking underage. Scout's little sister Tallulah was cited last year in Hollywood when she was 17.
