Southern Charm star Kathryn Calhoun Dennis is owning her past and moving forward with her life.
"You know, it's been a long haul," she tells ET. "But I feel more me than I've ever felt in a long time."
Only ET was invited inside Kathryn's family home in Moncks Corner, South Carolina, for an exclusive chat. The 25-year-old is back for season four of Southern Charm after a stint in rehab for substance abuse.
"I'm really at peace with everything," she says. "Chaos is out of my life, luckily. And, I have two beautiful babies. What else could you really wish for?"
Those babies, 3-year-old Kensington and 1-year-old St. Julien, aren't in South Carolina with Kathryn, though. They're spending the summer with her ex, and Southern Charm co-star, Thomas Ravenel, in California.
Kathryn says season four is the first time she's filmed completely sober, so it will be a whole different experience for her and for fans.
"It's been wild, but a great experience," she shares. "That's gonna be through fresh eyes, and I think that it'll provide some new perspective, probably, on these people and on these situations that we have, and Charleston in general."
"You know, there's such a stigma around what I went through, and there shouldn't be," she adds. "What I went through wasn't just addressing drug, alcohol, whatever. It was more beneficial in, like, life skills. Honestly, in a way I feel like everyone should go to some type of rehab, because, you just learn so much about people and life, and I think that's really been key in, like, resolving my own issues."
The star calls the new season a "metamorphosis."
"I think that people will be surprised at how easygoing and normal I can be," she says. "It's going to be so different, and in good ways, I hope. I know they're good for me, but hell if I know about anything of the others."
Season four kicks off with a flash-forward, showing Thomas and co-star Landon Clements seemingly getting together, romantically. Fans will have to watch and see if that's truly the case, but Kathryn suggests that is exactly what we can expect.
"She's got her moment to move in," Kathryn says. "I think they're pretty equal, so maybe they found their equals. That's fine, but she'll never be around my children. I know that ... let 'em eat cake."
