Kelly Osbourne Sports a Short Skirt for Material Girl Launch (PHOTOS)

Kelly Osbourne’s proud of her slimmed down physique, so why not show a little leg?

Miss O did exactly that as she proudly attended the launch of Madonna’s Material Girl fashion line in Los Angeles on Thursday night. Kelly is the new face of the line, as she recently replaced Taylor Momsen in the spokeswoman role.

Sporting a floral miniskirt, Kelly also wore a polka-dot low-cut top and a denim jacket (denim is back!)
