Michelle Obama, Dolly Parton and Kacey Musgraves were the biggest winners at the 2019 Grammys — even though Musgraves was the only one of the three to take home a trophy.

Musgraves was visibly shocked when she was announced as the night's biggest winner for album of the year for her record "Golden Hour" which won earlier in the evening for best country album.

ALL THE WINNERS OF THE 2019 GRAMMYS

"I don't even know what to say," Musgraves said. "I am very thankful. Winning doesn't make my album any better than anybody else in that category."

While Musgraves' win finished off the three-and-a-half-hour star-studded affair, host Alicia Keys set the tone for the show with a somewhat rambling opening speech about music being our "global language" before shocking the audience by bringing Michelle Obama, Lady Gaga, Jennifer Lopez and Jada Pinkett Smith on stage.

"Music has always helped me tell my story," said Obama, whose appearance had the crowd roaring. "Whether we like country or rap or rock, music helps us share ourselves. It allows us to hear one another."

Gaga told the crowd: "They said I was weird, that my look, that my choices, that my sound wouldn't work. But music told me not to listen to them." She had several other big moments during the show, taking home three awards and performing "Shallow" from "A Star Is Born."

The opening contrasted with last year's Grammys, where male acts dominated in nominations and the only woman competing for the top award, Lorde, didn't get a chance to perform onstage.

Cardi B made history as the first solo female to win best rap album (Lauryn Hill won as a member of the Fugees at the 1997 Grammys).

She was shaking onstage as she tried to give a thank-you speech with her rapper-husband Offset holding her arm.

"The nerves are so bad. Maybe I need to start smoking weed," she said as the audience laughed. "I just want to say thank you everybody that was involved ... I want to thank my daughter."

Perhaps the biggest moment of the night was when Katy Perry, Miley Cyrus, Maren Morris, Kacey Musgraves and Little Big Town all performed with MusiCares Person of the Year Dolly Parton. The crowd went wild while Parton and her fellow artists ticked through a medley of the country legend's greatest hits.

Lopez also had the crowd on their feet when she performed a Motown tribute inserting her energetic dance-pop flavor into memorable Motown melodies such as "Dancing Machine" and "Dancing in the Street."

She faced backlash on social media for her lead participation in a tribute recognizing an historic African-American record label.

Some online questioned why a black artist wasn't chosen instead of Lopez, but she did receive support from Smokey Robinson, who joined her in a duet to perform "My Girl," a song he co-wrote.

She then briefly teamed up with Alicia Keys on "Papa Was a Rollin' Stone" and sang "Another Star" with Ne-Yo, who played the piano.

HOST ALICIA KEYS UNAWARE SHOW RETURNS FROM COMMERCIAL BREAK

Another shining moment for female artists came as British singer Dua Lipa won the best new artist Grammy Award after performing a sultry duet with St. Vincent. Earlier in the show, H.E.R. wong the best R&B album for her self-titled album.

Ariana Grande also had a big reason to celebrate when she won best pop vocal album for "Sweetener." But the singer, who this week publicly clashed with a Grammys producer, did not attend the show despite having won her first Grammy.

The superstar accused Grammy producer Ken Ehrlich of lying about discussions with Grande about performing at Sunday's ceremony. Ehrlich told The Associated Press on Thursday that Grande had told producers that she said she didn't have adequate time to prepare.

Grande blasted the comments in a social media post, saying she could have prepared a performance overnight.

Another artist who won an award but did not attend the show was Childish Gambino, who is the alter ego of singer-actor Donald Glover. His song "This Is America" won the Grammy Award for record of the year.

Rapper Drake, who was rumored to not attend the show, surprised audiences when he did show up to accept best rap song for "God's Plan."

Another memorable moment came when Diana Ross took the stage in an uplifting performance of a pair of her classics in honor of her forthcoming 75th birthday.

Introduced by her grandson and wearing a dress of flowing bright red chiffon, Ross told the audience Sunday night that "when I was a little girl, I felt the joy of singing. It made me happy, it made my parents happy, and it led to this day."

Other performances including Miley Cyrus with Shawn Mendes, country duo Dan + Shay, Camila Cabello with Ricky Martin, Young Thug, and J Balvin, Brandi Carlile among others.
