Two of country music's ambassadors are coming together for a must-see musical event. That's right: Carrie Underwood and Miranda Lambert are finally teaming up for their first-ever song collaboration. At this year's May 18th Billboard Music Awards, these powerhouses will be debuting their forthcoming "Something Bad" duet live from the MGM Grand Garden Arena stage.

Lifted from Lambert's upcoming Platinum disc (out June 3rd), the song is expected to be an "in your face" kind of thing, as Lambert has teased on more than on occasion. "I'm a huge Carrie Underwood fan," Lambert tells Billboard in a statement on Wednesday (May 7). "'Somethin' Bad' is a meshing of our styles and there aren't many female collaborations in our format so I'm really excited to be debuting it on the Billboard Awards."

Previously, Lambert has teased her high hopes for the accompanying video--seriously, why would they do a music video if it's not a single at some point? Exactly. "Two girls, from Texas and Oklahoma, that are living their dream right now," she told the Associated Press in March. "We're really rocking in country music. If you're sitting on the front row, you might want to scoot back."

On the song itself, she explained that "it's a force, you know what I mean? It just feels exciting. I'm ready to rock. Singing with Carrie really pushes me. It's been too long since two girls in our genre have come together like that." Of course, Lambert admitted to being pretty scared by Underwood's vocal range,  "Singing with [her] is very, very intimidating."

How exactly did she ask Underwood to join her? Through a long, awkward email. She explained: "Asking her to do this was nerve racking. I sent her this long blabbing email about if she wanted to sing on the record: it could be cool but maybe she didn't want to and if she liked the song but she didn't have to like the song. When I sent it, I thought, 'this sounds ridiculous.'"

Underwood and Lambert are just the latest additions to the Billboad Music Awards. They join previously announced performers Miley Cyrus, Ricky Martin, Jennifer Lopez, Pitbull, 5 Seconds of Summer, Florida Georgia Line, Jason Derulo, Imagine Dragons, Luke Bryan, John Legend and OneRepublic.

Presenters include Jordin Sparks, Kelly Rowland, Pete Wentz and Wiz Khalifa.

Underwood is also up for the night's biggest honor, the fan-voted Milestone Award. She faces off against OneRepublic and Ellie Goulding. Fans can continue voting through to the end of the two-hour show.

The 2014 Billboard Music Awards air live on the ABC Network on Sunday, May 18 at 8/7c.

Of course, Underwood and Lambert have light the stage on fire together several other times, including during a concert in 2011. Their performance was, of course, rather electric, as they fused together their two biggest hits, "Before He Cheats" and "Gunpowder and Lead." If their recorded duet has anything to say about it, it just might become the song of the summer.
