Jonas Brothers Tug At The Heartstrings With Their Surprising Live Lounge Cover: Watch

'Seriously we can't stop singing this tune'

Jonas Brothers may have scored a No. 1 hit in the U.S. with their comeback single "Sucker," but across the pond, they faced stiffer competition. "Sucker" came oh-so-close to topping the U.K. chart, but Lewis Capaldi's gut-wrenching breakout ballad "Someone You Loved" ultimately edged it out of the top spot. The brothers have a totally chill attitude about it, though — on Thursday (May 30), they used their BBC Radio 1 Live Lounge appearance to cover Capaldi's hit and prove there's "nothing but love" between them and the Scottish singer.

As for the cover itself, Joe and Nick traded verses before beautifully harmonizing on the chorus, giving the ballad a faithful rendition that proves they're true fans — afterwards, they tweeted, "Seriously we can't stop singing this tune. It's been a problem all day." Capaldi, meanwhile, reacted in typically hilarious fashion:

Besides their cover of "Someone You Loved," Jonas Brothers also busted out a funky version of "Sucker," the lead single from their upcoming album, Happiness Begins. Check that out below.
