The ad, which teases a "sneak peek of the astounding entertainment to come" at the upcoming 3,500-room luxury destination, features Bryan as a fisherman interacting with his fellow American Idol judge Katy Perry, who portrays a mermaid. Underwood is showcased on her own floating tropical paradise.
The commercial also features EDM stars Zedd, who collaborated with Maren Morris on the hit song "The Middle" and Tiësto and Vegas mainstay Celine Dion.
"The concept of Stay Fabulous captures the essence of the Resorts World Las Vegas brand where guests are encouraged to embrace their individuality and create their own version of fabulous," Scott Sibella, president of Resorts World Las Vegas, said "With stunning visuals and special appearances from A-list entertainers, the commercial gives a peek into the incredible experiences that await when our doors open this June."
This will mark the first Vegas residency for Underwood and Bryan, who'll join fellow country artists George Strait and Shania Twain with shows in Sin City. Strait launched Strait to Vegas in 2016, while Twain's Let's Go! Residency kicked off in 2019.
This will also mark Perry's first Las Vegas residency.
Underwood recently released her gospel album My Savior and performed a gospel medley with the legendary CeCe Winans at the 2021 ACM Awards.
Bryan, the newly crowned ACM Entertainer of the Year, recently tested positive for COVID-19, leaving him unable to appear in person on the 2021 ACM Awards. Bryan recently returned to season 18 of American Idol after missing the first live show of the season due to coronavirus.
