The "Lose You to Love Me" singer stepped out to the Microsoft Theater in Los Angeles on Sunday, in a vibrant hue that certainly got everyone's attention.
Gomez, sporting an adorable '90s-style lob, rocked a satin lime green strapless Versace mini dress with ruffled detail and matching pointed-toe pumps. She styled the bright ensemble with a layered diamond choker, keeping the rest of her accessories to a minimum.
Inside the show, Gomez slipped into a second dress, which featured bright yellow satin on the top and was embroidered with green-and-orange lace at the bottom.
Gomez is set to open Monday's show with a performance of her new music, including "Lose You to Love Me." This will be her first live TV performance in two years. Her bestie and Artist of the Decade honoree, Taylor Swift, will also take the stage.
The 27-year-old brunette beauty recently announced the release date of her upcoming album, which will drop on Jan. 10. Her last album, Revival, was released back in 2015.
