Southern Charm star Kathryn Dennis is using sexual assault allegations from two separate women against her ex to help bolster her effort to get custody of the couple's two children.

The 27-year-old Bravo star filed new court documents in response to her ex, Thomas Ravenel, 56, and his attempt to keep their current joint custody arrangement in place.

In the documents, which were obtained by The Blast, Dennis raised allegations that Ravenel sexually assaulted two women and paid one for her silence as proof he should not maintain custody of their little ones.

In the midst of the sexual assault allegations, Ravenel submitted his own filing in the custody battle with Kathryn Dennis which was obtained by People.

In that filing, he accused her of acting 'for the purpose of garnering media attention, creating material for her storyline on Southern Charm and ensuring her marketability as a 'reality TV star.''

In Kathryn's recent response she refuted that claim and, according to The Blast, raised 'other incidents of bizarre behavior arising out of [Ravenel's] intoxication due to a mixture of alcohol and prescription drugs.'

She also claimed to be concerned with his 'admission that he has locked the kids in their rooms at night on occasion, which she fears is a safety hazard.'

Previously, Dennis has lost custody after failing a drug test but had fought hard to win back the joint-custody in their current agreement.
