It's unclear when exactly Kelly gave birth, but she sparked speculation in November that she had gone into labor when she shared a cryptic message to Instagram.

At the time, the television personality wrote on her Instagram Story, "OK, here we go," on a black backdrop. Kelly has been silent on social media ever since that post.

The daughter of Sharon, 70, and Ozzy Osbourne, 74, revealed she had a bun in the oven in May, posting a photo to Instagram of herself holding a sonogram.

"I know that I have been very quiet these past few months so I thought I would share with you all as to why," Kelly wrote alongside the upload. "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! 🤰💜."

Shortly after Kelly's post, her boyfriend followed suit with a photo of the ultrasound machine, captioning the post with a series of emojis, "💕❤️👨‍👩‍👦❤️💕."
