Kelly Osbourne is pregnant with her first child. The former reality star - who is currently dating Slipknot band member Sid Wilson - announced the big news in an Instagram post yesterday. “I know that I have been very quiet these past few months so I thought I would share with you all as to why,” she began, before revealing: “I am over the moon to announce that I am going to be a Mumma. To say that I am happy does not quite cut it. I am ecstatic!” Kelly is Sharon and Ozzy Osbourne’s daughter.
