Sid Wilson, the mask-wearing turntablist for SLIPKNOT, and Kelly Osbourne, the 38-year-old daughter of Ozzy and Sharon Osbourne, welcomed their first child together, a baby boy named Sidney. The news was revealed by Sharon on her U.K. current affairs television show “The Talk”.

Speaking on the January 3 episode of “The Talk”, Sharon said Kelly and Sid‘s son was named Sidney and she told her co-hosts: “[They’re] just so, so great. So great. [Kelly] won’t let a picture go out of him. No, and I’m so proud of her.”

Last October, Kelly revealed that she and Sid were expecting a son. She told Entertainment Tonight that Ozzy was excited that to finally be getting his first grandson, since Kelly’s brother Jack Osbourne, 37, has four daughters. Kelly said that she was “really excited” to become a mom and she praised her parents for their “incredible” support throughout her pregnancy since Wilson has been away on tour. “Every milestone I’ve kinda gone through with my dad, and he’s been great, even though he sometimes says the wrong thing,” Kelly added. “I’ll walk into the room and he’ll go, ‘Wow, you’re big.’ and I’m like, ‘Thanks, Dad’.”

Osbourne and Wilson first met in 1999 when SLIPKOT were booked onto that year’s Ozzfest line-up. Kelly and Sid became friends and stayed in touch over the years before the went official as a couple. Kelly shared in a Valentine’s Day Instagram post last year, “After 23 years of friendship I can’t believe where we have ended up! You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson.”
