After sweeping the big four Grammy Awards just weeks ago, Billie Eilish was on hand at the 92nd Academy Awards last night to deliver a special performance. Joined by her brother FINNEAS, the two shared a rendition of The Beatles' "Yesterday" for the customary In Memoriam segment honoring all those the film industry lost this past year.

The first person recognized during the performance was Kobe Bryant, who was killed in a tragic helicopter crash with his daughter Gianna and seven others just two weeks prior. When speaking with Entertainment Tonight, Eilish revealed how difficult it was trying to rehearse while seeing his face.

"It's just sad. It's like, I don't know what else to say," she said. "Every time, when we were in rehearsal and they run kind of what's going to be playing, every time I see his face, I'm like what? It's so weird. It doesn't make sense to me. I just got shivers, it's horrifying."

Bryant, who won an Oscar for animated short Dear Basketball in 2018, was one of many honored during the In Memoriam segment last night at the Academy Awards. Press play below to watch Eilish's touching performance.
