Washington: Kelly Osbourne, who recently broke her foot and had no idea what had caused it, has finally discovered that it was from her over-zealous use of the treadmill.
"This week the doctor finally found out how I hurt my foot,” Contactmusic quoted her as writing in her Closer magazine column.
"Running too hard on the treadmill caused me to pull the tendon away from the bone and give myself stress fractures. Now it’s just a matter of time until it heals properly and gets back to normal.
"Thank god, because I was starting to get sick of people looking at me like I was a lunatic when they asked me how I did it and I couldn’t answer,” she added.
