Country upstart Kelsea Ballerini will be stretching her wings at this Sunday's (Feb. 12) Grammy Awards. Linking up with soul-pop breakout group Lukas Graham, Ballerini makes the biggest move of her career so far with what should be one of the night's most talked-about moments. No word yet on what the two will be performing, but rumor has it it could be a mash-up of their two biggest hits, "7 Years" and Ballerini's own "Peter Pan." The starlet tweeted a video announcement on Tuesday morning (Feb. 7), and it featured footage from both acts' recent music videos. "You ready?" she asked. So ready.

Other country names expected to hit the big stage are Carrie Underwood with Keith Urban (for the primetime debut of their new single "The Fighter"), Sturgill Simpson, four-time nominee Maren Morris with Alicia Keys, Little Big Town with Demi Lovato, Tori Kelly and Andra Day, and more.

Ballerini is up for the all-genre Best New Artist, alongside Morris, Anderson .Paak, Chance the Rapper and The Chainsmokers. Morris' nominations also include Best Country Album (for Hero), and Best Country Song/Solo Performance (for "My Church").

59th Grammy Awards go live Feb. 12 at 8/7c.
