Kelly Osbourne has opened up about the biggest argument she's ever had with her partner Sid Wilson—and it was over their baby son Sidney's last name.
"This is personal, and I didn't expect to ever talk about this, but I'm going to. It's the biggest fight me and my baby's father have ever, ever, ever had, and probably ever, ever will was over naming our son," Kelly told her parents Ozzy and Sharon on their podcast The Osbournes.
