Demi Moore and Bruce Willis' wild child daughter, Scout, got caught naked and frolicking with pals in the pool at Hollywood's famed Chateau Marmont after a raucous night partying, RadarOnline.com has learned.
After boozing with up to 25 friends inside a luxurious private suite on Friday, Sept. 13, the 22-year-old Tinseltown scion stunned bug-eyed hotel staffers who watched as she stripped off her floral printed dress and splashed into the water for a giggly skinny-dip in the early hours of the next morning.
"Scout was the first to impulsively take the plunge, then about 10 of her friends followed suit -- or suit-less," joked our spy witness.
"There was a lot of whistling and hooting!"
We're told Scout was later quietly warned that proper swimming attire must be worn at all times!
"Scout's sister Rumer was spotted at the party earlier in the night but she had gone before everyone decided to go butt-naked," revealed our source.
Scout is no stranger to risqué behavior: At age 20, the aspiring singer was arrested in New York City's Union Square for giving cops a fake ID after being nabbed with an open beer.
In May, Moore failed to attend Scout's commencement ceremony at Brown University in Providence, Rhode Island, though father Bruce and her stepmom Emma Hemming were there and proudly showing off their support.
