The diva certainly had a Cinderella moment.

In true diva fashion, Ariana Grande shut down the red carpet for a few minutes this evening because her dress was so large. It was revealed the grey-hued oversized ball gown was a whopping 20 feet in diameter, leaving little room for others to snap photos. 

The statement dress complete with a voluminous tulle skirt was a custom design by Giambattista Valli. Apparently, the Italian designer rarely does personal jobs. Of course, that was not the only custom ensemble piece. The 26-year-old also had Christian Louboutin shoes made and outfitted with grips on the bottom to prevent the singer from slipping.

So, it was fitting Grande's stylist Law Roach revealed the inspiration for the whole look was simple: princess. But, the "7 Rings" songstress stuck to tradition when it came to the hairdo as she wore it up in her signature ponytail. 

It was everything you'd expect from the self-professed diva who is nominated for five Grammys, including Album of the Year and Best Pop Vocal Album. Although, Grande won her first Grammy last year. But, she boycotted the show when producers wouldn't let her perform the song of her choice. 

As far as her connection to Giambattista Valli, this wasn't the first time the pop star wore a dress by the designer. Grande wore a pink peplum and black lace skirt from the Fall 2015 Couture Collection to the 2015 American Music Awards. 

Other stars like Kendall Jenner, Amal Clooney, and Rihanna have also made statements in the designer's gowns. Jenner wore a dramatic look to the Cannes while Clooney wore one of his ensembles during her wedding festivities. "The first exit with the short dress on her wedding was a smashing moment," Giambattista said of Clooney's look. "It was not about me – it was about her. She was magical in it."
