All the Stars (and Their Cute Kids!) at 'The Little Mermaid' Premiere in Hollywood

Halle Bailey

Ariel herself shined in a custom mermaid-esque gown by Valdrin Sahiti. Speaking to PEOPLE on the red carpet, Bailey gave a nod to princesses like Brandy and Anika Noni Rose who "were the blueprint for me to even be able to be here today." She added, "I hope that [Black girls] know they are worthy and we deserve to be in these spaces. And I hope that they see themselves in me on the screen. I'm just grateful to be here."

Melissa McCarthy

Meanwhile, costar McCarthy — who plays Ursula — opted for sea blue as she walked the carpet with husband Ben Falcone and their youngest daughter, Georgette, 13.

"I think it's incredible," Diggs, who plays Sebastian in the film, told PEOPLE of Bailey's casting.

I'm also thrilled that it is Halle, of anybody. She's wonderful."

Halle Bailey & Jodi Benson

Benson, who voiced Ariel in the original 1989 Disney animated movie, shared a moment with Bailey following the screening.

"She doesn't need any advice from me!" Benson told ET on the red carpet. "She's brilliant. I did get to meet her a few times and chat with her and just tell her how proud I was of her, and I love that she has a purity of heart and a pure spirit, and you can see that vulnerability and that childlike bravery and courage coming through, and it's beautiful. I'm so thrilled for her and I'm so proud of her."
