in 2018, with Hailee Steinfeld as a special guest. 2019–present: Charlie In August 2019, Puth released "I Warned Myself"; another single, "Mother", was released in September, and a third, "Cheating on You", in October. In early 2020, Puth announced that he had scrapped what he had written for his third studio album; he remarked in 2022 that he "didn't really like any of the music" he released in 2019, and that he "felt like [he] was kind of pretending to be a cool guy". He released "Girlfriend" in June and "Hard on Yourself", featuring Blackbear, in August. In September 2021, Puth released "After All" with Elton John as part of John's album The Lockdown Sessions. The same month he started documenting on TikTok a process of "combin[ing] a seemingly random bunch of thoughts and noises made with different objects into a pop song", which went viral on the platform; this led to the release of "Light Switch" on January 20, 2022, as the first single from his third studio album, Charlie. This was followed by "That's Hilarious" in April and "Left and Right" featuring Jungkook in June. On July 7, Puth revealed Charlie cover art and its release date. "Smells Like Me", "I Don't Think That I Like Her", and "Charlie Be Quiet!" were all released in September. Charlie was released on October 7 along with a music video for its song "Loser". Personal life Growing up, Puth was bullied at school. He said, "They would team up against me so bad and they would kick me in a place that wouldn't feel fantastic and I would need to throw up and they would then say I was pretending to throw up." On On Air with Ryan Seacrest he said he had a nervous breakdown from "just being overworked—and I'm in my head a lot and that, in combination with jetlag and, you know, the self-realization that I am getting more famous and my privacy goes out the window pretty much every day—it's just not what I'm used to, and I don't think I'm ever going to be used to it, and my therapy is to just put melody to it and sing it." Puth started collaborating with clothing brand Hollister Co. in 2017. He said that Justin Bieber's "viral leap into superstardom as a result of YouTube" influenced him to attempt the same.
