"*Some* of these people are absurd," he wrote. "Thankful for you! Oh, and my stomach is still recovering!"

Dennis — who is mom to son Saint Julien Rembert, 5, and daughter Kensington "Kensie" Calhoun, 7 — just told PEOPLE earlier this year that she's been planning for her future in her "low drama" relationship with boyfriend Chleb Ravenell, including babies.
The reality star added that Chleb is "really great" with her kids, whom she shares with ex Thomas Ravenel (no relation to Chleb).
"I really do want more kids, and my family isn't done being built," Dennis said. "That experience definitely made me realize that one day I do want that with him. I really mean it when I say that, too."
"It's very much an adult relationship, he and I — and we've definitely become much more of adults over the last year," she continued. "I'm just so excited that I really do feel like I have a partner."
