This sex podcaster says she got screwed — by her best friend.

Sofia Franklyn, one half of the “Call Her Daddy” podcast, broke her silence about the sordid drama behind the breakup of her smutty show and friendship with her co-host Alexandra Cooper, 26.

On Tuesday afternoon, the 28-year-old took to her Instagram stories to accuse Cooper of stabbing her in the back while they were renegotiating their contract with Barstool Sports. Franklyn also claimed they looked for outside deals to benefit their fans.

“I found out that Alex had gone behind my back and done something. And I found out it wasn’t the first time. And that’s why we’re here. I trusted Alex. I feel betrayed,” Franklyn said in the video.

Cooper, Franklyn and Franklyn’s boyfriend — HBO Sports honcho, Peter Nelson — did not respond to The Post’s requests for comment. Barstool declined to comment.

The Post reported that Cooper and Franklyn, who were trying to get out of their contract with Barstool Sports because they had other lucrative offers on the table, had turned on each other. In the middle of the schism was Nelson, who was allegedly shopping them around even though they were still under contract. His influence was reportedly said to be driving a wedge between the friends, who hadn’t recorded a podcast since early April.

On Sunday night, Barstool Sports founder Dave Portnoy commandeered their podcast to address the dispute, including jaw-dropping allegations that Cooper and Franklyn, who claim poverty on their podcast, actually pulled in nearly $500,000 in their first year. He said he also offered them a sweetheart deal that Cooper wanted to accept but Franklyn was balking at.

Franklyn addressed the controversy directly on Tuesday, in a video message to fans.

“There’s been a lot of crazy s – – t being thrown around and some of it is true, some of it is false,” she said. “Alex and I created ‘Call Her Daddy‘ together. March of 2018 we created it, the two of us. And at that time, we were best friends, roommates, arguably like sisters. Then we took the show to Barstool Sports.”

Franklyn acknowledged that Barstool Sports was responsible for turning them into an overnight success, but she and Cooper wanted to explore other options for many reasons — one of which was for the benefit of their fan base, which is known as the “Daddy Gang.”

Franklyn said the pair regrets how they went about their business dealings, but she claims they were eager to return to Barstool. That’s why they took a meeting with Portnoy, who then extended the sweetheart deal.

“This is where the story gets extremely f - - ked up,” she claimed, adding that Cooper went behind her back but didn’t offer any details.

“I am willing to do ‘Call Her Daddy’. I really am. I just can’t do it under the circumstances that she wants,” she said, claiming “she is demanding that she controls the show.”

She continued: “We are partners. We have always been that way. We’ve always been 50/50, and so it’s put me in an extremely tough position. So here we are.”

She then thanked her fans, who stuck by her.

“I can’t even put into words how much it has meant to me… I remember when I quit my job for all of us to become a family or a gang or whatever, and I will be eternally grateful. You guys are the reason I am here.”

Franklyn, however, remained mum on accusations that Nelson — who many of their fans are accusing of ruining the podcast — was behind the drama and didn’t even mention his name.
