"Come & Get It," indeed! While performing her hit song at the Billboard Music Awards at the Las Vegas MGM Grand Garden Arena, Selena Gomez looked hotter than ever, rocking a sexy gold, cleavage-baring bodice.

Keeping the rest of her onstage ensemble fairly simple, the singer, 20, chose to wear her hair down and go completely barefoot -- matching her eyebrow-raising outfit with gold colored-jewels on her forehead and a bindi to complete her Bollywood-inspired look.

The former Wizards of Waverly Place actress was introduced by the show's host, comedian Tracy Morgan**, who first flubbed Gomez's name during his opening monologue, calling her "Celine."

However, Morgan made nice with Gomez before her performance, referring to her as a "role model" to his daughter.

"My daughter loves Selena Gomez," he said. "She's a role model to girls. That's why Selena, you gotta do a song about listening to your father...call it, 'Yes sir, right away sir.'"

The Spring Breakers actress and her off-and-on love, Justin Bieber**, declined to walk the blue carpet together.

Gomez's relationship status seemed to be far from her mind before the music event, tweeting on May 18 that she was feeling "#excitednervousanxious" about her performance.

Her upcoming album, Stars Dance, is due out this summer.
