Kelly Osbourne is offering an inside look at what she calls the "biggest fight" she and boyfriend Sid Wilson have had throughout their relationship, disclosing candid details about the "huge" disagreement about their son that seems to have finally come to a close.

The mother of one, who welcomed the couple's 15-month-old, also named Sid, in late 2022, opened up about the argument on a recent episode of her family's podcast, The Osbournes Podcast, describing the tot's last name as "the biggest fight me and my baby's father have ever ever ever had, and probably ever ever will."

It turns out that baby Sid, who currently only has his father's surname, will soon share his mother's, too, after the two finally came to an agreement over a year after his birth.

The 39-year-old admitted she wasn't happy about the fact that her son didn't share her name, something her beau didn't understand until their big blowout, which led to "eye-opening conversations and some couples therapy."

"This is personal, and I didn't expect to ever talk about this, but I'm going to," she told her parents. "I wanted our son to have both of our last names, and he wouldn't let me...I feel that I was forced into doing something I didn't wanna do and I can never ever forgive him for that, but we can move on."

She added, "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. Not one is more important than the other."

Kelly acknowledged that Sid comes from a very "traditional" family, understanding why hyphenating their last names could be difficult for him at first, but, as Sharon Osbourne replied, "It's a very dated mentality."

The first-time mom kept details of Sid's birth private at first, until her parents blew her cover, with her mother revealing his name on her daytime talk show before Kelly was ready.

The new mom later shared a note via a recent Instagram Story, writing, "I am not ready to share him with the world. It is no one's place but mine to share any information on my baby."
