Hilary Duff is a charitable, wholesome actress.
But that doesn't mean the 19-year can't get down with her drunken self from time to time.
Reportedly, January 25 was one of those times. Hilary and older sister Haylie showed up - where else? - at L.A. club Hyde with a huge entourage.
The younger Duff - who has been single since splitting in November from Good Charlotte rocker Joel Madden arrived arm-in-arm with her sister after 11 p.m., looking tipsy already.
Soon enough, Hilary was teetering over to the women's restroom with one of her girlfriends, in a very vomit-ous state. Perhaps she was trying to drink away the pain of Madden hooking up with Nicole Richie.
"It was kind of inappropriate," a witness said. "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 Britney Spears-style throughout the night at a VIP table, where sources say 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 unidentified older man.
We can't say for sure who it was - but does anyone know where Kevin Federline was that night?
