America's Got Talent‘s Grace VanderWaal Risks Wardrobe Malfunction in Backless Look at TIFF

Grace VanderWaal's got talent when it comes to turning heads at the 2024 Toronto International Film Festival.

In fact, the America's Got Talent winner wasn't afraid to show some skin as she stepped out for the Sept. 10 premiere of Megalopolis, rocking a daring look made up of a backless pink corset and a skirt that could cause a wardrobe malfunction with its plunging waistband.

Grace turned to independent artist Liam MacKenzie for her custom bodice, which featured rose-like embellishments, ribbon ties and a feathery collar.

The 20-year-old paired the dramatic top with a black Cinema By Panos Zinas number that she and stylist Elza Khalife sourced from the Desert Stars Vintage store in Brooklyn, N.Y.

"Liam you’re an artist through and through thank you so much for making me feel so special," Grace wrote on Instagram following the event. "Dream team styling here, all NYC based of course."

And New York has certainly captured Grace's heart since winning AGT in 2016 at age 12. Recently, she appeared on one of TikToker David Carmi's viral Confidence Heist videos, in which he asks Big Apple residents their secrets to being confident while out on the streets.

"Having somewhere to go makes you look confident," Grace shared in the Aug. 14 clip, "because you're just in a rush."

But the "I Don't Know My Name" singer noted that she developed a thick skin from growing up in the spotlight.

"It threw me into scrutiny," she explained, "and just kinda forced me to sink or swim."

And in Megalopolis, Grace got to tap into her vocal talents, playing a popstar opposite Adam Driver, Aubrey Plaza, Nathalie Emmanuel and Giancarlo Esposito. Last year, director Francis Ford Coppola shared how he ended up casting the "multi-talented" Grace in his movie, revealing that their ties went back years ago when he befriended her dad David VanderWaal while researching film equipment.

"He told me about his young daughter who was writing songs and gaining notice," the Oscar winner recounted on Instagram, adding that their paths crossed again years later when Julia Hart—the daughter of Bram Stoker's Dracula screenwriter James V. Hart—casted Grace in the 2020 Disney film Stargirl. "All these threads came together, eventually resulting in casting Grace to star in and write songs for MEGALOPOLIS."
