Celebrity Celebrity Family Celebrity Family Dynamics Russell Simmons Blasted by Ex Kimora Lee Simmons and Daughters: 'Enough Is Enough' "We won't be bullied threatened or afraid," Kimora Lee Simmons wrote via Instagram on Monday By Ashley Paige Updated on June 20, 2023 12:00PM EDT Just one day after Father's Day, Russell Simmons appears to be at the center of a massive family feud. On Monday, the Def Jam Recordings executive shared an Instagram Story that seemed to target his ex-wife, Kimora Lee Simmons. "Stop telling fathers they should have fought harder to see their children & start asking mothers why he had to fight at all," the post read. Simmons, 48, took to her own Instagram Story to share details behind the family tension, where she lobbed serious allegations against the father of her two children, Ming Lee, 23, and Aoki Lee, 20. "I'm so sorry to have to do this," she wrote. "But this man has been threatening my kids' lives. I'm hearing so much more now. We won't be bullied threatened or afraid." Kimora Lee Simmons/Instagram "Leave my kids alone," she continued. "This narrative of attacking the only caregiver, the only parent in the home with the kids, the mom, AND the kids for one's own shortcomings and embarrassments is dead. Dead. Dead." Kimora Lee Simmons/Instagram The model also accused Russell of being "abusive" to the women in his life. "The same abusive ish," she wrote. "This is how you manouver [sic] with the women all around you. Your threats and lies and intimidation manouvers [sic] and tactics are sad. Stop it please. Your own flesh and blood? Enough is enough."

A rep for Kimora Lee Simmons did not immediately reply to PEOPLE's request for comment. Kimora Lee Simmons/Instagram Aoki, who just graduated from Harvard, backed her mom, posting a video of Russell appearing to yell at her over FaceTime to her Instagram page. She captioned it, "This is not someone who will accept help. This is just one screen recording sorry I don’t always remember to press 'record' when he calls my friends, my boyfriend, anyone, to get a chance to threaten and curse and go crazy." She also shared screenshots of text messages between her and her father to her Instagram Story, where she said he'd "harass" her boyfriend and friends if she blocked him or "[took] some space." Kimora Lee Simmons' 5 Kids: Everything to Know Kimora Lee Simmons/Instagram In another thread posted online by Aoki, texts — seemingly from Russell, although a name is not shown — imply Aoki's "mother has stolen money and the love of my kids as she promised." Aoki vehemently defended her mom in the messages, writing, "I'll never speak to you until you DIE. Don't ever say that again." Kimora Lee Simmons/Instagram In a separate lengthy message to her father, Aoki wrote, "Everytime I spoke to you you would yell and scream about a legal situation that I can't even respond to because I AM NOT INVOLVED, I am your child, not your lawyer your ex wife any of it. I can do nothing. You yell at me like it's my fault."

"We all defended him against anything, and then he suddenly turned on ANYONE who will let him lash out." "It's a really just terrifying change to watch,” she wrote.
