Musicians and guests attending the 60th Grammy Awards wore white roses in solidarity with Hollywood's anti sexual harassment movement 'Time's up'.
Musicians including including Rita Ora, Miley Cyrus and Cardi B as well as host James Corden wore white roses as artist's used the ceremony to speak out against sexual harassment.
Host James Corden said the show had the "most diverse group of nominees" in Grammy history, which rapper and music mogul P Diddy also celebrated online.
However, Alessia Cara was the only female artists to win an award on her own merit, with Rihanna featuring on Lamar's winning track LOYALTY.
Cara said she was wearing a white rose to show support to women not just in the entertainment industry.
"Things are uneven and unequal and they need to be talked about and they need to be changed," she said backstage after winning her award.
Lady Gaga, performing all in white, also gave a nod to the celebrity-backed anti-harassment initiative between songs.
Janelle Monae, introducing a performance by Kesha, also called "Time's Up" on the "abuse of power", saying the music industry is also affected by sexual harassment.
"It's not just going out in Hollywood, it's not just going on in Washington it's right here in our industry as well," she said.
"Just as we have the power to shape culture, we also have the power to undo the culture that does not serve us well."
A Grammys sketch showing Hillary Clinton reading passages of Michael Wolff's explosive account of life inside President Donald Trump's White House, Fire and Fury, received a mixed reception.
The former Democrat candidate for US leader was part of a skit starring the likes of John Legend, Snoop Dogg, DJ Khaled and Cardi B.
The Grammy Awards host James Corden was auditioning the musicians - and eventually Ms Clinton - for the audio recording of the best-seller book.
Trump's son, Donald Trump Jr, hit out at Clinton on Twitter, saying: "Getting to read a #fakenews book excerpt at theGrammys seems like a great consolation prize for losing the presidency."
He later added: "The more Hillary goes on television the more the American people realize how awesome it is to have @realDonaldTrump in office."
US United National Ambassador Nikki Haley also slammed her appearance on the music awards show, saying on social media: "I have always loved the Grammys but to have artists read the Fire and Fury book killed it.
"Don't ruin great music with trash. Some of us love music without the politics thrown in it."
However, some viewers disagreed with one calling the sketch the "best segment of the night".
It was not Ms Clinton's first appearance at the Grammys. In 1997 she won for reading her book It Takes a Village.
The night belonged to Bruno Mars who won all six of the awards he was nominated for including record of the year and album of the year.
Jay-Z who entered the show leading the way with eight nominations walked away empty-handed, being overshadowed by his younger contemporary Kendrick Lamar who won five.
British singer Ed Sheeran, who did not attend the awards, bagged two gongs for best pop vocal album with Divide and solo performance with Shape Of You.
The singer, whose third album Divide broke dozens of records and was the second biggest selling of the year, failed to make the shortlist for the main categories.
And fellow Brits Sam Smith and former One Direction members Harry Styles and Niall Horan were overlooked at the 60th Grammys in New York that took place just 12 months after Adele beat Beyonce to album of the year.
Country singer Maren Morris dedicated a performance to victims of the bombing at the Ariana Grande concert at Manchester Arena and those killed in the massacre at the Las Vegas festival where she had performed.
Awards were also given posthumously to Leonard Cohen, for best rock performance, and Carrie Fisher, for best spoken word album with her reading of her memoir The Princess Diarist.
