Ozzy, Sharon, Jack and Kelly Osbourne all attended the Fox Winter All-Star Party last night, held at "My House" in Hollywood, California. It was a real family affair as all four members stepped onto the red carpet to form a united front. 

Although we couldn't help but notice, as flawless as she looked, Kelly didn't look so happy. Perhaps after going it alone in London for so long, a night with her parents was just a little too much?
