Osbourne, 38, welcomed her first child with boyfriend Sid Wilson.
Kelly’s mom Sharon Osbourne confirmed the baby’s arrival during an appearance on the UK version of “The Talk.”
Sharon revealed that the baby’s name is Sidney. She added, “[They’re] just so, so great. So great.”

Along with photos of her ultrasound, she wrote, “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. To say that I am happy does not quite cut it. I am ecstatic! 🤰💜.”
It is unclear when Kelly gave birth but in November, she posted a cryptic Instagram Story, writing, “Okay, here we go.”
Kelly’s brother Jack just welcomed his fourth child in July.
Along with a pic of his newborn daughter Maple in a bear onesie, he wrote, “Aree and Maple are doing great and are happy and healthy.”
