Kelsea Ballerini shines on 'SNL' stage: Watch

Kelsea Balleirni reached the penthouse of late-night television this weekend with a debut performance on "Saturday Night Live."

The country-pop hitmaker performed two songs on the tastemaking sketch comedy show, including a stirring piano-and-vocals rendition of "Penthouse" — a standout number from "Rolling Up The Welcome Mat," the singer's surprise post-divorce EP that debuted last month. Ballerini, a 29-year-old Tennessee native, split from ex-husband and fellow singer Morgan Evans last August after a nearly five-year marriage.

Dressed in head-to-toe white, Ballerini belted, "Kissed someone new last night/ But now I don't know where you're sleeping, baby/ We got along real nice, until I wanted out, now I know you hate me."

Earlier in the show, Ballerini performed the pop-soaked "Blindsided," also from her "Welcome Mat" project." A six-piece band backed the singer as a silhouetted dancer mirrored her performance behind a blue-and-white screen. During the song, she tossed a little fuel on her post-divorce creative fire by adding a new line that seemingly called out Evans' new breakup single "Over For You."

At the end of "Blindsided," Ballerini sang, “Now you’re singin’ it loud on the radio like you’re the only heart that breaks/ You would’ve searched the whole world over? Yeah, sure, OK.”

On this week's edition "SNL," Ballerini joined Kansas City Chiefs tight-end Travis Kelce, who made his hosting debut nearly three weeks after winning his second Super Bowl.
