You wouldn't know it to look at her, but Kelly Osbourne ended her paso doble in pain.
The unexplained injury that resulted in her gingerly dancing the group hustle in bare feet also led to a visit to the Cedars-Sinai Medical Center emergency room immediately following tonight's taping of Dancing With the Stars.
Turns out the buckle of Kelly's shoe slammed into her foot at the end of the routine. The extent of her injury is unknown, but the accident caused her enough pain that she eschewed shoes moments afterward for the group number.
"At the end of our paso doble Kelly banged her foot on the floor, which may have caused an injury," her partner, Louis van Amstel, tells E! News. "She is at the hospital right now to take an X-ray and an MRI to make sure she will be OK to dance. Kelly will keep me updated on her prognosis."
Ozzy Osbourne, whose tune "Crazy Train" was the musical accompaniment to her paso doble, was with his little girl at the hospital.
Here's a recap of how all the celebs did tonight on Dancing With the Stars.
