Kelly Osbourne has revealed that she is pregnant with her first child!

The 37-year-old former reality star - who is currently dating Slipknot band member Sid Wilson, 45 - announced the happy news in an Instagram post on Thursday.

"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!"

The daughter of Sharon and Ozzy Osbourne revealed the news with two images on her Instagram page - where she has 2.4million followers - showing her relaxing poolside while looking at her sonogram pictures

Kelly confirmed her new relationship with DJ Sid - known for playing turntables in the heavy metal band Slipknot - in January this year when the pair went Instagram official.
