The incident – which is outlined in Parker's $1 million lawsuit – occurred in in the summer of 2020. She told us she was not in the then-couple's hotel room when Hanks arrived, which apparently set him off.
"He sent me over 15 messages, saying all kinds of crazy things. That was the start of the abuse," Kiana told Radar, providing us two photos showing alleged text messages between the then-couple. "I didn't think it was gonna get this serious, where he was gonna put his hands on me, but those were signs that should have clicked. I should have walked away then."
The first photo shows 18 texts sent from Hanks to Parker, starting with "WHERE U AT."
He went on to write, "kiana I'm not f--kin playing," "Where are you" and "I swear On everything if you don't send me your location right now we're gonna have a problem." He then sent her 13 consecutive messages that said "Location," followed by "KIANA."
The second photo shows Chet expressing regret, though it is unclear what preceded it.
"I didn't mean any of that s--t. But I'm really disappointed in myself for saying it," he wrote Kiana, who responded, "I just Don't [know] if this is a sign. That s--t hurt. What if I brought up rumors about ur family or just hit you where it hurt." She added, "Idk man."
That's when Chet alleged that he "watched my mom domineer and control my dad for my entire life and he just sat there and took it. When I feel like I'm not being respected as a man it strikes a nerve with me because it makes me feel like I'm allowing the same thing to happen to me and I'm becoming what I hated most in my father."
"So talking about me & pushing up on me make you feel more of a man," Kiana replied. "Again if I said anything about your family business or rumors you would be looking at me crazy."
Reps for Chet, Tom and Rita have not yet responded to our requests for comment.
Parker did not say whether Hanks was drinking before or during the incident but did tell us he had fallen off the wagon by that point, which allegedly prompted his parents to cut him off financially.
"He was tossing me around, throwing things. That's the night he called me a 'ghetto Black b---h' and a lot of hurtful things," Kiana said as her voice trembled. "It was just different after that day"
She said that she and Chet got locked out of their room during the scuffle, which ended up spilling out into the hallway, and that he had to call downstairs and make up a lie about how they got locked out while getting ice.
"That's like a five-star hotel," she told us. "They bring you ice."
After the alleged incident, Kiana said Chet "apologized" but told us she still felt uncomfortable about it all.
"I didn't share this story with anyone, not even my mom, and she's like my best friend. I was just embarrassed. I didn't want to tell anyone," she said. "And he made remarks like, 'No one will believe you. I'm a Hanks.' All those things. And I listened! I thought it wouldn't happen again, and months later, it was even bigger."
"He thinks he can get away with anything because of who his parents are, but that's not right," she added. "You can't go around treating and putting your hands and abusing women. You just can't do that. And trying to use your name as an excuse?"
Though the case is ongoing, Parker told us her relationship with Hanks is "definitely over" and that they have not spoken since she filed.
Since the "life-changing" New Orleans incident, Kiana says she's been seeing a therapist weekly.
"I'm just trying to get back some balance," she told us. "It's a life-changing event. Some days I wake up, and after I do my meditation and pray, I look at my phone, and some days it's a lot of messages or emails, and sometimes they're not nice. Sometimes they're death threats. It's just crazy and can be overwhelming some days."
Despite her anxiety, Parker is hopeful she will receive justice because she "was always taught that what you do in the dark will always come to the light."
