In an October 2022 interview with Howard Stern, Puth revealed he was in a relationship, though he didn't give away too many details, such as his girlfriend's identity. "[She's] someone that I grew up with," he said. "She's always been very, very nice to me and I would assume that when times inevitably are hard in the future, because what is life without valleys and peaks, she would be there for me as well."
On Dec. 2, Puth confirmed in an Instagram post that his secret girlfriend is Sansone. He wrote in the caption, "🎶 Ohhhhh I'm NOT a loser…'cause I didn't lose her!!! 🎶 (Happy birthday to me.)" Sansone, 23, shared the same photo in her Instagram Stories, as well as a video of Puth performing taken from backstage.
According to her LinkedIn, Sansone is a digital marketing and PR coordinator. She attended high school in Red Bank, NJ, which is right next to Rumson, where Puth is from. Her brother shared a photo of Puth and Sansone together on Instagram back in October.
While Puth said he's very much in love, he told Stern if he does propose, don't expect to read about it anywhere. "If I do, certainly the media won't know about it," he explained in October. "I'll go out of my way to make sure they don't know."
