Whitney Elizabeth Houston (August 9, 1963 – February 11, 2012) was an American singer and actress. Nicknamed "The Voice", she is one of the best-selling recording artists of all time, with sales of over 200 million records worldwide. Houston has influenced many singers in popular music, and is known for her powerful, soulful vocals and vocal improvisation skills. However, her personal problems began overshadowing her career. Her 2002 studio album, Just Whitney, received mixed reviews. Her drug use and a tumultuous marriage to singer Bobby Brown received widespread media coverage. After a six-year break from recording, Houston returned to the top of the Billboard 200 chart with her final studio album, I Look to You (2009). On February 11, 2012, Houston accidentally drowned in a bathtub at the Beverly Hilton hotel in Beverly Hills, with heart disease and cocaine use as contributing factors. News of her death coincided with the 2012 Grammy Awards and was covered internationally.

Charles Otto Puth Jr. (born December 2, 1991) is an American singer, songwriter, and record producer. His initial exposure came through the viral success of his song videos uploaded to YouTube. Puth initially signed with the record label eleveneleven after performing on The Ellen DeGeneres Show, while songwriting and producing for other artists. With primary intent on a solo career, Atlantic Records and Artist Partner Group eventually sought the artist and released his debut single, "Marvin Gaye" (featuring Meghan Trainor), in 2015. His next single and first feature, "See You Again", which he co-wrote, co-produced, and performed with Atlantic label-mate Wiz Khalifa for the Furious 7 soundtrack as a tribute to actor Paul Walker. It peaked at number one on the US Billboard Hot 100 for 12 non-consecutive weeks. After the success of "See You Again", he gained worldwide recognition for multiple subsequent releases, including his next single, "One Call Away". The single reached number 12 on the Billboard Hot 100. Puth's debut studio album, Nine Track Mind, was released in January 2016 to moderate commercial success. The album was preceded by the singles "One Call Away" and "We Don't Talk Anymore" (featuring Selena Gomez), which peaked at number 12 and number 9 respectively on the Billboard Hot 100. In 2017, he released two songs, "Attention" and "How Long", with the former peaking at number 5 on the Billboard Hot 100. Both were included on his second studio album, Voicenotes (2018), with ameliorated critical reception and a peak of number 4 on the Billboard 200. In 2019, Puth released the singles "I Warned Myself", "Mother" and "Cheating on You". The following year, Puth released singles "Girlfriend" and "Hard on Yourself". After deciding not to put these songs on his next album and scrapping what other songs he had written for it in early 2020, Puth released "Light Switch" in January 2022 as the lead single of his upcoming third studio album Charlie, which is scheduled for a 2022 release. "Light Switch" peaked at number 27 on the Billboard Hot 100. The album's second single, "That's Hilarious", was released in April 2022.
