“Southern Charm” star Kathryn Dennis is fighting for primary custody of her two children — and is using the sexual assault claims against Thomas Ravenel as ammunition in her battle.

Dennis wants a South Carolina judge to deny Ravenel’s request to maintain their joint custody arrangement for Kensie, 4, and Saint, 3, citing Debbie Perkins and Dawn Ledwell’s claims that he assaulted them, per court documents obtained via The Blast.

Dennis, 27, argued that Ravenel, 56, “cherry-picked” parts of a court-appointed doctor’s report in 2017 stating they were both fit parents and recommended co-parenting, adding the doctor was unaware of the allegations against him at the time.

Page Six reported that Perkins’ daughter Ashley accused him of assaulting Debbie after a Tinder date gone wrong earlier this year, and her allegations prompted his children’s former nanny, Ledwell, to come forward with her claims that he assaulted her in his bedroom. He was arrested on assault and battery charges in September in regard to Ledwell’s claims, and the case is headed to trial. In the meantime, Ledwell is suing him, NBCUniversal, Bravo, production company Haymaker and Comcast over the incident.

Bravo and Ravenel parted ways after the allegations were made, but Dennis is using Ravenel’s on-again-off-again girlfriend Ashley Jacobs’ defamatory comments against her from the last season of the show as another reason that Ravenel’s request should be denied.

Dennis also claimed that she is concerned with Ravenel’s “incidents of impulsive anger,” saying: “He admitted to [her] that he has locked the children in their rooms at night on occasion, which is clearly a major safety hazard.”

Finally, she alleged there are “other incidents of bizarre behavior arising out of his intoxication due to a mixture of alcohol and prescription drugs” and insisted that she is not seeking primary custody just for a storyline.

Ravenel’s lawyers did not return our request for comment.
