Lady Gaga
In February 2019, it was reported that Gaga and Christian Carino, her boyfriend of two years, had called off their engagement. Later that month, Gaga won her first Academy Award, known as an Oscar, in the Best Original Song category for "Shallow". She performed the song alone at the 61st Grammy Awards but joined with Cooper at the Oscars. After the Oscars performance, the song became Gaga's fourth number-one hit on the Billboard Hot 100 and Cooper's first.
