19-year-old Hilary Duff reportedly got drunk at club Hyde with her sister last Thursday and was seen teetering into the women's restroom with one of her girlfriends and a flamboyant male friend.

"It was kind of inappropriate," the onlooker sneers. "She was pretty drunk and staggering around the bathroom, bumping into people and shrieking that her gay male friend had a vagina so it was okay for him to be there." The sisters continued to party Paris Hilton-style throughout the night at a VIP table, where our source says they were "all over" their two man-dates. Haylie 21, whispered in the ear of her 30-ish-year-old date while kissing his neck. Hilary perched on her date's lap, laughing and flirting with her own older man. Says the source: "When I've seen Hilary out in the past, she has been relatively composed, but tonight she was acting pretty wild."

I'm confused here. I always thought Hilary Duff was the good one. While Paris Hilton and Lindsay Lohan were snorting cocaine off bathroom floors Hilary Duff was the one driving her boyfriend away by refusing to have sex with him. And now this? Next you're gonna start telling me she's not a real live horse-woman. It's like my whole world is turning upside down!
