Lady Gaga has had an emotional awards season for her film with Bradley Cooper, "A Star Is Born", and the tears began flowing early on Grammy night as the singer took to Twitter Sunday to celebrate both Grammy and BAFTA wins.
The 32-year-old entertainer was joined on stage by the song's co-writer Mark Ronson while performing live during the show.
The track will compete for more Grammys, including song of the year, record of the year and best pop duo/group performance.
Cardi B, who was to perform later on Sunday, could break that trend and take home not only her first Grammy, but potentially become the first rapper since 2004 to win the coveted album of the year award for her "Invasion of Privacy".
At the age of 85, country star Willie Nelson won best traditional pop vocal album for My Way. Check out the full winners list now!
"I'm not gonna be able to wear any makeup tonight", Gaga tweeted.
"It was when my creativity & self expression was stifled by you, that i decided not to attend. i hope the show is exactly what you want it to be and more", she continued.
The biggest stars in music have descended on Hollywood for the 61st annual Grammy Awards.
This year's show exhibits some efforts to combat these diversity issues - the academy, which The Times reported has invited 900 new members to vote, expanded major categories from five to eight nominees.
"The performance is based off of my grandma's childhood, and I have my family in the performance", she said on the red carpet. "So you can take all that disgrace, Mr. Pence, and you can look yourself in the mirror and you'll find it right there". "I support her and I support her decision", she added.
What will the final speech from Neil Portnow - who caused more than a little consternation previous year when he said women needed to "step up" in order to secure broader inclusion - contain? Kendrick Lamar leads with eight nominations, followed by Drake with seven and Brandi Carlile with six.
Ariana Grande has said no thanks to the Grammy Awards. "Thank you so much for this gift I am completely shocked". But it was female artists who dominated nominations in the top categories.
Sunday's show will include performances by Diana Ross, Miley Cyrus, Post Malone, Dolly Parton, Janelle Monae, Shawn Mendes, Katy Perry, Ricky Martin and Red Hot Chili Peppers.
A performance honoring the legacy of the late "Queen of Soul" Aretha Franklin is also expected.
