Julia Fox has urged women not to have children with "losers".

The 'Uncut Gems' star has hit out at her ex-husband Peter Artemiev for allegedly having their four-year-old son Valentino baptised without her permission or participation and then claiming she had told him she wasn't interested in being there.

In a rant shared to TikTok, Julia concluded: "Girls, please, from the bottom of my heart, who you have a child with will dictate the rest of your life.

Do not have a child with a loser."

Julia had told how she only found out about the baptism from a chance remark made by Peter.

She said: "So basically, what happened was, I went to my son's school for his school performance. His dad was there. He came late, as usual.

"And then I had to, like, help load some stuff in my car, so we were walking to my car, and he points to this church, and he goes, 'Oh, this is where Valentino was baptised.'

"I was like, 'Well, why wasn't I invited?' And he was like, 'You were invited; you just didn't want to come.'

"And I was like, 'Okay, first of all, don't tell me what I was not and was invited to.' Like, absolutely not. If I was invited to something like that, I would go. I would remember. And if I wasn't invited, I would still have a picture or something. Like, no one told me anything about this."

After Peter allegedly continued to claim Julia "didn't want to be" there and "didn't care" about the religious ceremony, she was taken back to times in their romance when she felt like she was "being gaslighted over and over and over until then I freak out and then do something and he calls me abusive."

Julia ultimately called Peter's mom to ask why she wasn't invited, and Valentino's grandmother told her the priest had said it was a "Russian Orthodox thing and only Russian Orthodox people could come."

She added: "And it's like, 'Wow, now I see where this man gets it from.' Don't gaslight me. That is a b******* excuse. I am this child's mother. You are not his mother."

After claiming Peter's mother told her she thought she "didn't care", she fumed: "I've been raising this child alone for four years, doing everything for him, taking him all around the world with me on any job I do, and you think I don't care?

"I was like, 'Listen, lady, your son doesn't care. I care very much, and you just robbed me of an experience.'"

The call prompted Peter's mother to ask if she'd be "punished" by not being able to see Valentino, but Julia insisted she doesn't "operate like that".

She added:

"It's just crazy, like you can't make this s--- up. These people are f------ animals," she said, before bringing the camera closer to her face and adding a plea to all of her female followers. "Girls. Please. Please from the bottom of my heart. Who you have a child with will dictate the rest of your life.

Meanwhile, Peter claimed his mother had called Julia in February 2024 to ask permission to have Valentino baptised.

He added to People magazine: "Her response to my mom was... 'I don't care about religion. If you want to baptise him. Baptise him. I don't care.' "
