Teen sensation Billie Eilish won the first of the top four prizes at the Grammy Awards on Sunday, taking home the song of the year statuette for her hit single "Bad Guy."
Eilish, an 18-year-old newcomer, also won for her pop album "When We All Fall Asleep, Where Do We Go?" beating Taylor Swift's "Lover," while her older brother Finneas was named non-classical producer of the year.
"Wow! So many other songs deserve this," said Eilish. "I genuinely want to say I am so grateful and I am so honoured to be here. I grew up watching all of you."
Eilish and fellow fresh faces Lizzo and Lil Nas X dominated the early awards in a live show that was dedicated to basketball star Kobe Bryant, who died in a helicopter accident earlier in the day.
The young trio are going head to head for the other top prizes - an album of the year, the record of the year and best new artist - presented at the end of the 3-1/2-hour live telecast.
"Tonight is for Kobe" said Lizzo, kicking off the show with a medley of the title song from her album "Cuz I Love You" and hit single "Truth Hurts."
The Grammy Awards took taking place at the Staples Center in Los Angeles, the home of Bryant's team the Los Angeles Lakers.
"We are literally standing here heartbroken in the house that Kobe Bryant built," said Grammy host Alicia Keys. "We never imagined in a million years we'd have to start the show like this."
Lizzo won three of her leading eight nominations, including the best urban contemporary album for "Cuz I Love You," and pop solo performance for "Truth Hurts," beating established artists like Beyonce, Ariana Grande and an absent Swift.
Gay black rapper Lil Nas X, 20, wearing a cowboy hat and silver lurex suit, and country singer Billy Ray Cyrus brought the house down with a kitschy performance of their viral collaboration "Old Town Road," with contributions from stars ranging from K-Pop band BTS to young yodeler Mason Ramsey.
"He told the world he was gay and overnight he became an inspiration and a role model for hundreds of young people around the world," comedian Ellen DeGeneres, who is also gay, said as she introduced Lil Nas X, who won two early Grammys.
Grande performed a medley of hits from her Grammy-nominated break-up album "Thank u, Next," including "7 Rings" and "Imagine."
Slain rapper Nipsey Hussle, 33, who was gunned down in his Los Angeles neighbourhood last year, won best rap performance for "Racks in the Middle," and was honoured in a tribute by John Legend, DJ Khaled and rapper Meek Mill.
Blake Shelton and his fiancee Gwen Stefani held hands as they debuted their new romantic duet "Nobody But You," while Camila Cabello sang her recent single "First Man" to her tearful father in the audience. Demi Lovato won a standing ovation in her first performance at a major awards show since a drugs overdose in 2018.
The Grammy winners are chosen by members of the Recording Academy, which is currently embroiled in a dispute over the departure of its new chief executive Deborah Dugan and her allegations of conflicts of interest in the nominations process. The Recording Academy has denied the allegations.
