The cast of The Summer I Turned Pretty recently put their honesty to the test in a Vanity Fair lie detector challenge, and the results were equal parts revealing and hilarious. Stars Lola Tung, Gavin Casalegno, and Christopher Briney took turns answering awkward, funny, and personal questions while strapped to the polygraph machine. The video, released on YouTube, gives fans an intimate look at the trio’s off-screen chemistry and playful banter.

Lola Tung Opens Up

Lola Tung, who plays Belly, kicked things off. She admitted to keeping childhood diaries under lock and key, though she laughed when pressed on what secrets they contained. The test also revealed her true fandom for Cher—though under pressure, she hilariously blanked on song titles before redeeming herself with “I Got You Babe.” Tung also spoke about attending Taylor Swift’s Eras Tour with series creator Jenny Han, confirming that Swift acknowledged them in the crowd with a heart gesture. When asked if it was the greatest moment of her life, Tung said it was a big highlight, but not the single best.

Gavin Casalegno’s Golden Retriever Energy

Next up was Gavin Casalegno, known for his role as Jeremiah. He shared that he once modeled for JCPenney as a child, a start that eventually made him hyperaware of fashion. When asked about the show’s frequent shirtless scenes, he admitted it was a production requirement rather than his choice. Casalegno also revealed he limits himself to four minutes on Instagram each day, meaning he no longer reads all of his DMs. However, he didn’t shy away from confessing that for a hypothetical $2 million, he would indeed sell pictures of his feet—a revelation his castmates will likely never let him forget.

Christopher Briney Keeps It Real

Finally, Christopher Briney took the hot seat. The actor, who plays Conrad, spoke about his time working at Trader Joe’s and revealed that his worst job was actually in a call center during college. When asked who was the better actor between Lola and Gavin, he diplomatically chose Lola, praising her ability to carry the show. He also admitted to being worried about typecasting after playing brooding heartthrobs in both The Summer I Turned Pretty and Mean Girls. His dry humor shone through when asked how much it would take for him to sell feet pictures—he joked it would cost “billions” unless the buyer was a friend.

Why Fans Love These Tests

The segment showcased the trio’s easy camaraderie, blending playful teasing with candid insights. From Tung’s Swiftie moment to Casalegno’s Instagram time limits and Briney’s candid career worries, the test gave fans plenty to talk about. For a series that thrives on romantic tension and emotional storytelling, this behind-the-scenes look reminded viewers why the cast has such undeniable chemistry both on and off screen.
