Kelsea Ballerini shipped her new single, “The Other Girl,” to country radio on April 20.

“The Other Girl, which was penned by Kelsea, Shane McAnally and Ross Copperman, features vocals from pop star Halsey. The new tune is the second single from Kelsea’s 2020 self-titled album, following her Top 20 lead single, “Homecoming Queen?”

Kelsea and Halsey recently teamed up for the 70th episode of CMT Crossroads, which aired in March.

While Kelsea, 26, has scored five No. 1 hits on the country charts since dropping her debut album in 2015, Halsey, 25, has earned a handful on No. 1 songs on the pop charts since releasing her 2015 debut album, including “Him & I,” “Eastside” and more.

As Kelsea told Kix Brooks of American Country Countdown, collaborating with your friend makes “perfect sense.”

“We are [friends],” says Kelsea to Kix. “I’ve always wanted to do a CMT Crossroads—I love collaborating—but I always wanted to do it with someone that I was comfortable with. You’re doing nine songs with that person, so it’s like you really want to be able to connect to their music and just them as a person, and so Halsey and I have been friends for a couple of years now and, it made perfect sense to kick it off with Crossroads.”
