The #SouthernCharm mom had some harsh words about his parenting skills.

Kathryn C. Dennis may have given birth to her and Thomas Ravenel's second child just last November, but now the Southern Charm mom is criticizing the real estate developer's involvement in raising their kids.

It all started after Thomas posted the below photo of himself with another woman on Instagram on Valentine's Day.

Though it's unclear what Thomas' relationship is to the woman in the picture, Kathryn seems to not have been happy about this Valentine's Day present from her baby daddy. "Where are u now that I need ya? And your kids need ya? Oh wait. With some hoe traveling the country. #***hole," she tweeted Monday night.

Kathryn continued to attack Thomas' parenting (or lack thereof, according to her) of their daughter Kensie, who turns 2 in March, and three-month-old son St. Julien on Twitter Monday. "You can be a jerk to me...but not our babies. #iknowwhereyouatdummiecough DC cough palm beach and where are your kids? With moi. Safe," Kathryn wrote in one tweet. "@Thomasravenel asked for it & he gone get it. His vday to our babies? Had his groom [the person who takes care of his horses] return [Kensie's] high chair..on my porch..with rust/mold on it," she said in another.

Kathryn also said that she isn't receiving "a dime" of child support from Thomas.

@sukie_tawdry he calls it "a check of goodwill." But he also says he's not legally required to pay anything so he doesn't. Anymore. — Kathryn C. Dennis (@kathryn_dennis) February 16, 2016

It doesn't look like Thomas has responded to Kathryn's claims yet, but this probably won't be the last time she'll put him on blast. "Heller welcome to REALity," Kathryn responded to one Twitter user Monday. "My lips aren't sealed this year. If you thought they were before."

@CHASEatkins heller welcome to REALity. My lips aren't sealed this year. If you thought they were before 😉 — Kathryn C. Dennis (@kathryn_dennis) February 16, 2016

Buckle up, because things are about to get bumpy in Charleston. But here are some adorable pics of newborn Kensie, in case you need a break.
