Kelly Osbourne at Fashion Week

This year's Fashion Week has an unexpected star: Ozzy-spawn Kelly Osbourne! The 25-year-old has been everywhere, even on the runway for Naomi Campbell's show (center photo), looking very blonde and very thin. She credits her weight loss to pilates and her recent stint on "Dancing With The Stars." Hopefully she won't become too bobble-headed!

In other Osbourne news: this morning she Twittered, "i woke up covered in blood because a glass door exploded on my friend of [sic] the bathroom of the boom boom room last night!" The exclusive club is housed in the Standard Hotel on the High Line; could Andre Balazs be getting a lawsuit for Valentine's Day? The duo allegedly spent the night in the hospital after a glass panel fell on her friend and got embedded in her knees.
