Spencer Prattis calling the timeline ofKaitlynn CarterandMiley Cyrus‘ relationship into question.

“It’s tough for me to listen to Kaitlynn complain about people talking about her allegedly open relationship with Brody when we know she had a thing going with Miley,” Pratt wrote. “She already had something going on with her when these scenes were filming — maybe not physically, but definitely emotionally.”

“No one’s judging you for whatever it is you and Brody do when he’s not sleeping in his car,” he continued, referencing an earlier episode when Jenner, 36, slept in his car after the couple got into a fight. “We just don’t want people to lie about their lives.”

“Maybe you shouldn’t have gone on television,” he added. “It’s called a reality show, hon. And the reality is that Brody’s been talking about your sex life on his podcast for years.”

Reps for Cyrus and Carter have not commented, but Cyrus, whoannounced her splitfrom husbandLiam Hemswortharound the same time photos surfaced of her and Carterkissing in Italylast month, hasdenied being unfaithful during their marriage.

“I can accept that the life I’ve chosen means I must live completely open and transparent with my fans who I love, and the public, 100% of the time,” she tweeted on Aug. 22. “What I cannot accept is being told I’m lying to cover up a crime I haven’t committed. I have nothing to hide.”

Though Cyrus, 26, acknowledged her history of infidelity in past relationships, she insisted that she did not cheat on Hemsworth, 29.

“The truth is, once Liam & I reconciled, I meant it, & I was committed. There are NO secrets to uncover here,” she wrote. “I can admit to a lot of things but I refuse to admit that my marriage ended because of cheating. Liam and I have been together for a decade. I’ve said it before & it remains true, I love Liam and always will.”

On Monday’s episode, Carter, 31, said her costars lacked “common decency” when it came to keeping details of her and Jenner’s relationship to themselves. Pratt fired back in his recap, “I would love to know Liam Hemsworth’s thoughts on Kaitlynn’s recent displays of ‘common decency.’ ”

“You know what I call ‘common decency’? Getting it on at your Italian villa and not in front of the paparazzi,” he wrote.

“Brody Jenner and Kaitlynn Carter have decided to amicably separate,” their reps said in a statement at the time. “They love and respect one another, and know that this is the best decision for their relationship moving forward.”

“DoingThe Hillsmagnified a lot of things in their marriage,” the source said. “And it became clear that it wasn’t going to work. They both knew it.”

Despite Pratt’s allegations, Jenner hasonly spoken highly of his ex.

“There is far too much negativity being directed at someone who Ilove and care about very much,” he recently wrote in a since-deleted Instagram post. “I feel the need to set the story straight. Kaitlynn and I have been best friends for 6 years, and we continue to be. We, like many others before us and many after us, grew in different directions over those same 6 years.”

“Kaitlynn is a wonderful person, beautiful and fun to be with, always a positive force in my life,” he continued. “We decided the best move for both of us was to keep our love for each other strong but move forward separately with our lives. I respect Kaitlynn and care deeply about her. She deserves to be able to move forward in her life with respect and happiness.”

As for Carter and Cyrus? A source recently told PEOPLE they“live together and are very happy.”

“Miley is doing great,” said the source. “She is moving on. She seems to have no regrets. She loves being with Kaitlynn.”
