16 details from the Grammys that you might've missed

While presenting the award for song of the year at the beginning of the ceremony, Questlove seemed to joke about the moment Will Smith slapped Chris Rock at the Oscars last weekend.

Before announcing the nominees, he said, "All right, I'm gonna present this award, and I trust that you people will stay 500 feet away from me."

At the Oscars, Questlove won the award for best feature documentary, which Rock was presenting when the slap occurred.

The Roots front man later told Jimmy Fallon he was meditating and didn't even notice the incident happened before going onstage.

When Lipa and Stallion presented the award for best new artist, the two were wearing the same Versace dresses, featuring the brand's signature safety-pin design.

Stallion joked that Lipa "stole my look," and Lipa responded that she "had the exclusive."

Donatella Versace was even part of the bit. The designer came up and ripped bits of fabric off the musicians' outfits so they weren't identical.

The moment seemed to be a reference to the 1998 VMAs, when Mariah Carey and the late Whitney Houston walked on stage to present an award wearing the same dress.

Carey and Houston also made adjustments to their dresses to make them different.

Doja Cat, who was nominated for eight Grammys, walked the red carpet in a sheer mint-green Atelier Versace gown covered in Swarovski crystals.

But her accessories were the star of the show. She held a handblown glass Coperni handbag filled with what looked like hard candies in gold wrappers.

There was also a matching bedazzled JBL speaker attached to the purse.

Stallion made a statement in a look that featured three different types of animal print.

The rapper wore a leopard-print Roberto Cavalli dress that had a different animal print on the interior lining.

Her nail artist, Coca Michelle, also created a tiger-print manicure that featured the design of a tiger's mouth including the teeth, tongue, and a yellow gem.

Stallion finished off the animal-inspired look with snake earrings and a leopard broach.

During her performance of "Happier Than Ever," Eilish honored the late Taylor Hawkins by wearing an oversized T-shirt with his face on the front. His last name was also printed on the back in capital letters.

Hawkins was the drummer for the Foo Fighters, and he died nine days before the 64th Grammys.

The Foo Fighters were originally scheduled to perform at the ceremony, but the band canceled the performance after Hawkins' death.

When she walked the red carpet, Lipa wore a bondage-inspired Versace dress from the designer's fall 1992 collection titled Miss S&M.

Supermodel Cindy Crawford wore the same dress three decades earlier at the 1992 MTV VMAs.

But Lipa made the look her own by piling on thick gold necklaces and showing off matching gold nails.

Tinashe walked the red carpet in a bubblegum-pink GCDS gown, carrying a Coperni bag similar to Doja Cat's.

A closer look at Tinashe's curly updo revealed tiny pink jewels that matched the color of her dress.

She completed the look with pink eye makeup and lipstick.

New celebrity couple Antonoff and Qualley, who made their first public appearance in March, weren't shy when it came to PDA at the Grammys.

The two sat together and posed for photos with their arms around one another.

At one point during the show, while host Trevor Noah was introducing an award presenter, Antonoff and Qualley were in the background of the shot laughing, touching each other, and kissing.

Zauner of Japanese Breakfast made her Grammys debut in a bright-yellow Valentino Haute Couture dress.

She opted for a monochromatic look with sharp yellow eyeliner and acrylic yellow nails that featured 3D bubbles.

Lady Gaga and Tony Bennett were nominated for their jazzy collaborative album "Love for Sale," but Gaga performed solo at the ceremony.

Bennett submitted a prerecorded tape of him announcing Lady Gaga's performance, but he wasn't in attendance. The singer announced his retirement last year, shortly after revealing his Alzheimer's diagnosis.

Clips and photos of the two singers played in the background of the performance, and at the end, the pop star posed with her hand on her shoulder — mimicking photos the duo released to promote their album, with Bennett's hand resting on her shoulder.

Many fans interpreted the pose as a tribute to Bennett in his absence.

When Doja Cat and SZA won the Grammy for best pop duo/group performance, which Lady Gaga and Bennett were also nominated for, SZA was struggling a little to get on stage with crutches and a long tulle train.

Lady Gaga gave her a standing ovation when the duo was announced, and she helped SZA gather her train so she wouldn't trip going up the stairs.

SZA later told Variety that she was on crutches because she "fell out of bed."

To add to the drama of the acceptance speech for best pop duo/group performance, Doja Cat was notably missing as SZA made her way on stage.

Moments later, Doja Cat rushed through the room, and SZA said into the mic, "Bro, you went to the bathroom for five minutes. Are you serious? Come on now."

Out of breath, Doja Cat grabbed the mic and said, "Listen, I have never taken such a fast piss in my whole life. Thank you, everybody."

The singer then pretended to ring out the crotch of her dress.

Carlile, who was nominated for five awards, showed up to the Grammys in a custom Boss suit that was inspired by Elton John.

It featured multi-colored glass crystals on the jacket and pant legs.

During E!'s red-carpet coverage, Carlile told Laverne Cox that her jacket weighed about 40 pounds.

"I'm finally morphing into Elton John, which was my dream from day one," she added.

A representative for Carlile told Insider that the jacket actually weighed around 30 pounds.

On the red carpet, H.E.R. wore a beaded and embellished yellow-and-orange ombré jumpsuit that was inspired by Aretha Franklin's 1976 AMAs performance look.

"This is Peter Dundas, but Aretha Franklin was my inspiration tonight," she told People.

The sleeves were also embellished to resemble a phoenix.

Lavigne was a presenter at the Grammys, but her outfit paid tribute to her own album.

The singer wore a custom MOI MOI Paris gown with a tiered tutu skirt.

The waistband of the dress featured the words "Love Sux," the name of her latest album that came out in February.

Halsey walked the red carpet and made an appearance at the Grammys but left soon after BTS' performance, which was early in the show.

On Saturday, Halsey shared on Instagram that they had surgery a few days before the show.

The caption read, "The last time I attended the Grammys was 2017 and it was 3 days after I had my first endometriosis surgery. I walked the carpet with my stitches still in. As luck would have it, I'm attending tomorrow for the first time in years and I had surgery again (you guessed it) 3 days ago. Only posting this to say, if you see be gentle lol I'm fragile. Fragile but excited."

They later posted on their Instagram story, "Not feeling super well so I left early. Had to see BTS tho. Going to get some pasta and sleep. Thanks for everything luv u all."
