Puth was linked to singer-songwriter Charlotte Lawrence in early 2019. Rumours first circulated about the musically talented couple in February 2019, when Puth and Lawrence were spotted together several times during New York Fashion Week.
Puth confirmed their relationship in a since-deleted Valentine's Day Instagram weeks later. "Happy valentine's day," he captioned a picture with his arm around the 19-year-old singer. Lawrence responded to the post with a blushing heart emoji in the comment section.
Sadly, the happy couple didn't last. It's unclear exactly when they split up, but in September 2019, Puth tweeted, "Only because I want people to stop asking the question....Yes I am single now...and please don't believe everything you read...thank you."
Unless Puth dated someone else privately in 2019, Lawrence was likely the inspiration behind Puth's emotional breakup anthem, "That's Hilarious." In his 23 March, 2022, TikTok about the song, he had this to say about the making of the song: "I'm really excited for the song to come out, but every time I hear it, I'm kind of brought back to a time that was really, really challenging in my life," he said, adding, "It just brought me back to 2019, which was the f*cking worst year of my life."
