Kelly Osbourne is expecting her first child. 

The TV star shared the news via Instagram with a photo of herself holding an ultrasound picture.

"I know that I have been very quiet these past few months so I thought I would share with you all as to why… I am over the moon to announce that I am going to be a Mumma," Kelly captioned the post. "To say that I am happy does not quite cut it. I am ecstatic!"

Kelly has previously spoken about how her addiction hindered her from becoming a mother when she wanted to be.

"Yes, I feel very behind," Kelly said on an episode of "Red Table Talk." "As a woman, I would have loved to be married and have children by now. My brother [Jack] has three daughters and I would have loved to have kids by now, but that wasn't what was in the cards for me yet."

"I would have been no kind of mother at all," she explained. "Because I was that crazy addict that was like, 'Oh yeah, I'll stop doing drugs when I get pregnant because I have to.' Like, that's insane that I would ever even think that."

The "Fashion Police" star revealed she relapsed in April 2021 after nearly four years of sobriety.

"This is a little hard for me to talk about, but I’ve always promised you that I will always be honest with you about where I’m at and what’s going on in my road to recovery," Kelly admitted on her Instagram stories at the time. "I relapsed. Not proud of it. But I am back on track."

She later celebrated five months of sobriety via her social media in October.
