Fifth Harmony know how to work it, and with a new top 10 hit on their hands, the girl group is out to prove they're here for world domination. On Thursday (April 7), 5H hit up the BBC Radio 1 Live Lounge and gave their own spin on Elle King's breakout single "Ex's and Oh's." And, oh spoiler alert, they beyond slay it.

Describing the song as gritty with a blues and alt-rock lean (in direct contrast to other hits today), the girls were clearly Elle King fans. And they channeled that in their performance.

They ditched the dirty edge of King's, and instead emphasized the song's bluesy roots, with a standup bassline that sounded straight out of another time. The band wasn't the only ones on point, the girls themselves rocked it.

Sometimes, it's easy to forget that Fifth Harmony can, well, harmonize really well, but their chorus was particularly well laid out. And, unlike some of 5H's singles, each girl got her own moment to shine in the verse.

Tag this one up as yet another killer Live Lounge cover. Even Elle King herself even gave their rendition her approval.

While in the Live Lounge, Fifth Harmony also performed their new single "Work from Home," talked about their recent performance at Wrestlemania and listened to fan feedback from their performances.

Fifth Harmony is currently promoting "Work from Home," the lead single from their new album 7/27, which is due for release on May 20.
