Kelly Osbourne and Slipknot's Sid Wilson welcomed their little bundle of joy last year, and they are over the moon for the latest blessing in their life. However, there was a time when they fought hard while choosing the name for their baby; what happened?

The famed reality TV star recently appeared on "The Osbournes Podcast" to express her disappointment over her fight with her boyfriend.

According to Loudwire, their baby is named Sidney George Wilson IV, after his father. However, Osbourne opened up that there appeared to be confusion regarding the baby's name as they were unsure whether their son was the fourth Sidney George Wilson.

The TV host spoke to her mom, Sharon Osbourne, and dad, Ozzy Osbourne, in the episode of their podcast and noted that it was the "biggest fight" that she and Wilson had.

"The biggest fight me and my baby's father have ever, ever, ever had - and probably ever, ever will - was over naming our son," she said.

It didn't mean that the couple would separate for good, but she opened up that the pair had already spoken about their decisions and underwent couples therapy, and they finally reached a settlement; the baby will now have the last name of Osbourne-Wilson.

"We both made our child, so they should have both of our last names. Not one is more important than the other. But you have to remember, Sid comes from a really traditional English family," she added.
