Grammy Awards

Uncertainty around the Omicron variant means going ahead "simply contains too many risks", according to a statement from the Recording Academy and CBS.

The event, which is regarded as music's biggest night, was scheduled to take place on 31 January in Los Angeles.

It will happen on a future date to be announced soon, organisers said.

The health and safety of the music community, the live audience and hundreds of employees remained their top priority, they added.

The 18-year-old also won album of the year for her debut, When We All Fall Asleep, Where Do We Go, which was recorded in her childhood home in LA.

She replaces Taylor Swift as the youngest person ever to win the award.

"I joke around a lot at these things, but I genuinely want to say I'm so grateful," said the singer.

Eilish triumphed in all of the Grammys "big four" marquee categories - song of the year, record of the year, album of the year and best new artist.

She is the first person to achieve the feat since Christopher Cross in 1981.

The country star picked up best contemporary Christian song for God Only Knows, a duet with King & Country.

Rap star Lil Nas X also picked up his first Grammy in the best video category for his viral hit Old Town Road.

Many recipients have paid tribute to basketball star Kobe Bryant, who played for 20 years at the Staples Arena, where the Grammys are taking place.

Recording Academy CEO Harvey Mason Jr opened the pre-show, where the bulk of the night's 84 awards are distributed, by recognising the star's contribution.

Mars provided the night's big upset, taking the album of the year trophy that most critics assumed would go to Lamar's rap tour de force, Damn.

In the end, voters found Mars's crowd-pleasing R&B more palatable, while Lamar dominated the rap categories.

Alessia Cara won best new artist - making her the only female artist to win a major prize.

Stars like Lady Gaga, Kesha, Lorde and SZA were overlooked, with only 17 awards (out of a total of 86) going to women or female-fronted bands.

Frey died Jan. 18 of complications from rheumatoid arthritis, acute ulcerative colitis and pneumonia at the age of 67. Browne will join the Eagles' Don Henley, Joe Walsh, Timothy B.

Schmit and Bernie Leadon during a special performance during the show at the Staples Center in Los Angeles.

Browne and Frey wrote together early on in their careers, including the Eagles' first single in 1972 and one of their signature songs, "Take It Easy."

The Grammy Awards will be broadcast live from Los Angeles on CBS at 8 p.m. EST.
