Dennis, who shares two children with Ravenel, appeared onWatch What Happens Live with Andy Cohenon Monday where Andy Cohen asked her if she had anything to say about the allegations that he had sexually assaulted a woman he met on Tinder in 2015.

“Well, I’m waiting until the investigation is complete before I comment on anything. And right now my kids are my main focus,” Dennis said.

Her costar, Craig Conover, spoke up as well, saying, “All I know is what I’ve seen in the media, so it really wouldn’t be right for me to say anything at this point. I’m kind of just, I mean, I’m where everyone else is.”

Two women have publically accused Ravenel of sexual assault including his former nanny, who appeared on the Bravo show.

Earlier this month, real estate agent Ashley Perkins alleged to PEOPLE that her mother, Debbie Holloway Perkins, met Ravenel on dating app Tinder in October 2015 and went on a last-minute first date with him on Dec. 25 of that year. Ashley alsodetailedthe allegations on her website last month.

Ashley told PEOPLE her mother – who was not able to comment due to an alleged non-disclosure agreement with Ravenel as part of a $200,000 settlement – was allegedly attacked inside the star’s home.

“He pushes my mom onto the nanny’s bed, grabs her wrist with one hand, then he starts trying to pull her pants off,” Ashley said.

Ashley — who told PEOPLE she did not witness the alleged assault — said her mother “acted very withdrawn” after the date before she confided in her daughter that Ravenel “stuck his penis in my face.” She also accused Ravenel of holding her mom’s arms back and sticking his fingers inside her vagina and anus.

The second woman to allege the star assaulted her was Dawn, known to fans of the Bravo show as “Nanny Dawn,” who says she reported Ravenel to police on May 7 for allegations of sexual assault.

Detailing the alleged incident, Dawn claims that in January 2015, that Ravenel returned home from an evening with friends and attempted to kiss her.

After suggesting Ravenel go upstairs, Dawn said the incident escalated.

“I went upstairs to get my jacket which had the key to my vehicle in the pocket. I was corralled into the master bedroom and he shut the door behind me. I turned around and he had his pants dropped, not wearing underwear,” she said. “He was blocking the door. I was mortified, embarrassed, and scared.”

Without going into further detail, Dawn said she eventually got away from Ravenel, who she said is now being investigated for “first-degree forcible rape.”

“My client enjoys a certain degree of fame, which has unfortunately made him a vulnerable target for such claims,” Ravenel’s attorney, Richard P. Terbrusch, told PEOPLE in a statement earlier this month responding to Ashley’s allegations. He did not respond regarding Dawn’s.

The production company behind the hit Bravo series announced last week that they arelooking into the sexual assault allegationsagainst the 55-year-old reality star.

Ravenel, aformer South Carolina state treasurer, is currently datingAshley Jacobs.
