The 2015 Billboard Music Awards just got even more amazing, as Mariah Carey is scheduled to perform. It'll be her first time singing during the show in 17 years.

ABC News reports that over the course of her impressive career, Mimi's earned more songs on Billboard's Hot 100 chart than any other artist. Although we have yet to find out which song she'll perform during the show ("Infinity"? We're guessing/hoping), we're already excited to see her slay it.

Mariah is just one of many, many performers scheduled to appear during the show. Billboard previously announced that Kelly ClarksonEd SheeranMeghan TrainorJohn Legend, Hozier, Nick JonasSam Smith and Fall Out Boy featuring Wiz Khalifa would all take the stage.

Additionally, ABC News reports the list of presenters includes Rita Ora, Ne-Yo, Orange Is the New Black's Laverne Cox and the cast of the upcoming Entourage movie: Kevin Connolly, Kevin Dillon, Jerry Ferrara and Adrian Grenier.

If that's not enough to get you hooked, the 2015 Billboard Music Awards will be hosted by Ludacris and Chrissy Teigen.

“If my extensive collection of all 53 Now That’s What I Call Music compilations is any indication, I am both qualified and honored to join Ludacris in hosting this amazing show that spotlights the best music and artists of the year,” Chrissy told Billboard.

We have a feeling Taylor Swift will be gracing the stage a lot throughout the show. After all, the "Style" singer leads the nominations with a whopping 14 nods in 13 categories.

You can tune into the 2015 Billboard Music Awards when they air live on Sunday, May 17 at 8PM ET on ABC.
