NEW AFFAIR ALLEGATIONS ROCK “REALITY” RELATIONSHIP …

|| By FITSNEWS || Tired of being called out for her own affairs, reality television star and South Carolina scion Kathryn Calhoun Dennis is firing back … accusing her Southern Charm co-star and “baby daddy” Thomas Ravenel of having sex with one of her “best friends”

While she was pregnant, no less …

Dennis, 23, took to Facebook to level the allegation at her 52-year-old on-again, off-again beau – whose attempted political comeback in last year’s U.S. Senate race flamed out spectacularly.

(Well … with some help).

According to the fiery redhead – a direct descendent of former U.S. vice president John C. Calhoun – Ravenel “had sex with one of my best friends while I was pregnant.”

Whoa …

“I typically never retaliate, or rather acknowledge such disgusting behavior,” she added. “However, since he chooses to publicize our life, here’s just a *tid bit* of the truth.”

Dennis posted the message at around 4:00 a.m. Sunday morning.

It was deleted not long thereafter, but not fast enough …

Yikes …

Three days ago, Ravenel posted – and quickly deleted – a text message he obtained in which Dennis professed her love for another man named “Tan Tan.”

FITS has since been able to confirm Dennis’ message referred to Charleston, S.C. native Tanner Amerson (a.k.a. this dude).

Ravenel reacted to the news by pitching a social media hissy fit.

“What an idiot I am,” he wrote.

No argument here …

“The joke of it is that she said she was going to propose to me today,” Ravenel continued. “I’m great in business but my personal life sucks! … Not only that but she’s telling everyone that physically assault her which is not only hurtful but blatantly false. My lawyer is right. When I see her I should run. Right now I don’t know how it could be worse unless we lost our health. How did I let her take my heart. It was cold and on a perch. Now it’s completely vanished with not even an attempt for explanation.”

Jeez …

“Many believe Ravenel and Dennis’ antics are designed to boost ratings for (Southern Charm), but we know them both better than that,” we wrote earlier this week in response to Ravenel’s latest antics. “And based on everything we’ve seen, they really are this crazy.”

Indeed …

Southern Charm – which airs Monday evenings at 10:00 p.m. EDT on Bravo TV – drew 910,000 viewers last week. That’s up from its second season premiere of 870,000 but down from its first season peak of 1.2 million.

Will the latest lovers’ quarrel between its two stars ramp up ratings this week?

We’ll have to wait and see …
