Julia Fox, star of 'Uncut Gems,' is pursuing her ex-boyfriend from 'Dead Beat.'

Julia Fox revealed her separation from her husband, along with some unsettling charges against him, on Instagram last month.

Fox posted about pilot Peter Artemiev on her Instagram Story two days before Christmas, calling him a “dead beat alcoholic drug addict dad.”

The posts have already deleted, but The New York Post provided screenshots.

According to Fox, he hasn’t been paying attention since she wrote that “he can be found at most strip clubs, Lucien, Paul’s bbg, Casablanco, the streets, etc.”

"I simply don't want my son to be f-ed up because he thinks his father was gone or liked drinking and partying more than him," Fox wrote, expressing her fear for Valentino.

"How can you claim to care about women, mothers, and single mothers, but then be out here enabling the behaviour!!!" she pondered.

Make an effort!!! It's the holidays, so keep a smile on your face and see your kids!!! This man abandoned me with a 5-month-old child, a dog, a house, and ALL THE BILLS. It's incorrect!!!

“I was saddened to learn of Julia Fox’s utterly false statements made on social media by my co-parent, who is clearly struggling,” he said.

“I will not comment further out of respect for her privacy and to protect our child,” a source close to the couple said.
