Music maverick AR Rahman attends 61st Grammy Awards with daughter Raheema

The rapper dressed like a mermaid in the half shell, with pearls. Her look was put together by Thierry Mugler.

The former first lady was seen in a metallic outfit on the stage. Her look was curated by Sachin & Babi. Lending a hand opening the show, she earned a rousing welcome from the crowd in Los Angeles.

The Latino beauty donned a huge, white bejeweled hat which had a brim for miles and was embellished to match her dress of the same shade. She appeared relaxed in her Ralph & Russo look as she posed for photographers with boyfriend Alex Rodriguez, who wore a multicolored dress jacket.

The 'Shallow' singer chose a silver strapless sequin gown with a high slit and side ruffle, thanks to Celine.

The 'Roar' hitmaker arrived in a pink Balmain confection that prompted comparisons to a cake topper.

The Cuban-American singer who opened the Grammys appeared cozy in a long-sleeve sparkler of a bright pink gown with a high neck and open back, done by Armani Prive.

As for the guys, some went wild. Post Malone was in a light pink embellished jacket and matching pants.

The K-pop sensation BTS showed up in black tuxedos and colored hair, including purple and green.
