“Tonight is for Kobe,” Lizzo declared at the 62nd annual Grammy Awards, belting out the lyrics to “Cuz I Love You” as the show kicked off.

The “Truth Hurts” singer’s performance gave way to Alicia Keys, who is hosting the show for the second time and took a moment to honor the retired Los Angeles Lakers star Kobe Bryant. He was killed in a helicopter crash earlier in the day with his daughter Gianna and seven others near Calabasas, Calif.

“We’re all feeling crazy sadness right now,” Keys said. “We’re literally standing here, heartbroken, in the house that Kobe Bryant built.” The Grammys are held at the Staples Center, where Bryant spent most of his N.B.A. career.
