Kelly Osbourne says a major spat with her baby’s daddy, Sid Wilson, has led to a change of their 15-month-old son Sidney’s last name.

“This is personal, and I didn’t expect to ever talk about this, but I’m going to,” she revealed on a recent episode of “The Osbournes Podcast” in conversation with her parents, Sharon and Ozzy. “It’s the biggest fight me and my baby’s father have ever, ever, ever had, and probably ever, ever will.”

The 39-year-old TV host went on to explain that she wanted their son to bear both of their last names, but Wilson wouldn’t allow it.

“I feel that I was forced into doing something I didn’t wanna do,” she said.

“Right now, my son doesn’t have a double-barreled last name,” she explained. “But after lots of eye-opening conversations and some couples therapy, [Wilson] has seen the light. We are going to legally change our son’s name to have both of our last names.”

“We both made our child, so he should have both of our last names,” the former reality show star added.

Osbourne and Wilson, the 47-year-old turntable musician for heavy metal group Slipknot, have been in a relationship with since early 2022 and welcomed their son later that year. The pair reportedly first met when Slipknot played at Ozzfest in 1999 and remained good friends until starting a romantic relationship.
