Actress Kelly Osbourne got injured when her pet bulldog William hit her jaw with its head.
Kelly, 28, shared the incident on micro-blogging site Twitter, reports contactmusic.com.
"I have been punched in the face by men but nothing has hurt more than being head butted in the jaw by my bulldog William! my teeth even hurt. Why do my ears hurt so much considering it was my jaw that got hit," Kelly tweeted.
