Billie Eilish takes a clean sweep of the Big Four at the Grammys

She earned her trophies for her debut album, When We All Fall Asleep, Where Do We Go? and the single Bad Guy.

Taking to the stage for album of the year, she said: “I think Ariana (Grande) deserves this.”

“I love you, thank you for this,” she added.

Her older brother Finneas O’Connell, who co-wrote When We All Fall Asleep, Where Do We Go? and handled its production, said he was puzzled by the album win.

He said: “We wrote an album about depression and suicidal thoughts and climate change.”

Christopher Cross was the last artist to win all four major categories back in 1981.

Eilish denied Lizzo success, although she scored three gongs in some of the lesser categories – best pop solo performance, best urban contemporary album and best traditional R&B performance.

Lil Nas X also had a successful night, scoring two Grammys for best music video and best pop duo/group performance.

The night saw stand-out performances from Eilish, Grande and Camila Cabello with many artists including impromptu tributes to Bryant.

She perched on a stool as she performed the piano ballad When The Party’s Over.

Cabello reduced her father to tears with a heartfelt performance of First Man, a song about their relationship.

And Ariana Grande performed a risque medley of her songs including Seven Rings, and Thank You, Next, dressed in white heels, a fur jacket and stockings.

She was backed by an orchestra and singers in lingerie.

It comes after Grande cancelled her planned performance at last year’s event, accusing Grammys organiser Ken Ehrlich of refusing to allow her creative freedom.

Lil Nas X performed a high-energy rendition of his hit Old Town Road with K-pop boy band BTS, viral country singer Mason Ramsey, Diplo and Billy Ray Cyrus.

Bryant’s Los Angeles Lakers jersey was laid out on a chair in the background.

And during a joint performance, Run-DMC and Aerosmith held Bryant’s 24 jersey aloft.

The event also saw FKA Twigs, Sheila E and Usher pay tribute to Prince, who died on April 21 2016, performing a medley of songs including When Doves Cry and Kiss.

The awards opened with a tribute to Bryant after the retired basketball player was killed in a helicopter crash hours before the ceremony began.

A shell-shocked audience reflected on the death of Bryant, his teenage daughter and seven others in the Sunday morning crash.

Host Alicia Keys said the ceremony was cloaked in sadness following the deaths.

“We’re all feeling crazy sadness right now,” she said. “Because earlier today Los Angeles, America, and the whole wide world lost a hero.”

Keys, standing in the same arena where former Los Angeles Lakers star Bryant spent much of his glittering career, added: “We’re literally standing here heartbroken in the house that Kobe Bryant built.”

She said all the helicopter crash victims are “in our spirit, our hearts, they’re in our prayers, they’re in this building”.

She asked the star-studded audience inside the Staples Centre to remember the victims, adding: “We never imagined in a million years we’d have to start the show like this.”

Boyz II Men joined Keys on stage for a moving performance of their song It’s So Hard To Say Goodbye To Yesterday.

Earlier, nominee Lizzo performed two of her hit songs, Cuz I Love You and Truth Hurts, saying before she began: “Tonight is for Kobe.”

Fans gathered outside the Staples Centre to pay tribute, leaving flowers and wreaths.
