Convinced her ex was making things up, Madelaine Petsch called him back and snapped, 'You're a fu**ing liar. He didn't see you'
Blind trust can feel unshakable until one unexpected phone call reveals the entire facade. In a candid appearance on the podcast Call Her Daddy (@callherdaddy), "Riverdale" actress Madelaine Petsch opened up to host Alex Cooper about the only time she ever caught a partner in a major lie. Petsch explained that she completely believed her then-boyfriend had gone to sleep while she was away working on location. But one call from an ex-boyfriend, who told her what her partner was wearing at 4 a.m., changed everything. The YouTube episode posted on September 17, 2025, has racked up over 1 million views and 15,000 likes.
Petsch recalled that her boyfriend had called her earlier that night to say, "I just got home. Went to bed. I love you. Good night." Because she had "blind trust" in him, she didn't question a thing. A few hours later, her ex called her up. "Hey, I met your boyfriend last night at like 4:00 a.m.," he told her. Petsch immediately pushed back, asking, "Hey, no, he was in bed. Were you in bed with him?" She even accused her ex of lying and "being crazy." When she called her boyfriend the next morning to mention the strange claim, he doubled down, insisting, "No, no, I was at home."

Convinced her ex was making things up, Petsch called him back and snapped, "You're a fu**ing liar. He didn't see you." Instead of backing down, her ex began describing a very specific gift Petsch had bought for her boyfriend, something nobody knew about or featured on her social media. Her ex mentioned that he was wearing that night. Realizing there was no way her ex could have known about the outfit, Petsch paused and asked, "Wait a second, hold on. Where were you?" Her ex revealed that her boyfriend had been out at a bar with a "very famous '80s pop star," adding that "they were like all over each other."
When Petsch confronted her boyfriend again, he suddenly changed his tune, mumbling, "Oh, yeah, maybe I was there for like a second. I don't really remember." By 4:00 p.m. the next day, photos of the pair surfaced online, prompting Petsch to ask, "Hello. Do you think I'm stupid?" Even though she doubted he actually cheated, the blatant dishonesty was an instant dealbreaker, leading her to tell Cooper, "The lie was enough for me to be like, I'm done." When Cooper asked if she stayed with him, Petsch replied, "No. Fu*k no."

While Petsch's story sounds like a Hollywood script, relationship dishonesty is a common reality across the country. According to research published by the University of Copenhagen, lying in romantic partnerships consistently loses trust and triggers guilt, withdrawal, and rising suspicion. Furthermore, a 2009 study published in Human Communication Research found that while 59.9% of Americans reported telling no lies in a 24-hour period, 32.2% told between one and five lies, and 7.9% told six or more. As Cooper pointed out during the episode, gaslighting someone even after photo evidence surfaces only makes the betrayal worse.


In the YouTube comment section, viewers praised Petsch for being so open about her personal life, holding firm to her boundaries, and bringing a relatable energy to the conversation. @Tianachantale writes, "Madeleine balanced being open and honest with keeping her boundaries in place so incredibly graciously!" Meanwhile, @D.marie5587 said, "Okay, but when you guys get to the relationship talk…I just ended a 9.5-year relationship (5-year engagement) because I realized I deserve better and can’t continue into a marriage where it mimicked the catastrophes I saw growing up."
