"Hey loves!" Amy Heidemann and Nick Noonan wrote in the description of the video. "Looks like this was leaked this weekend, so we decided to put it on our YouTube channel for you! Thank you for the continued support, you guys are the best - xoxo."
'Brokenhearted' follows the band's first single, 'Crash Your Party,' along with several notable covers that put the spotlight on the Massachusetts natives. Both singles will be included on Karmin's forthcoming debut album, which is currently set to hit stores in April.
Karmin will make their first appearance on 'Saturday Night Live' on February 11 with host Zooey Deschanel. Traditionally, the show's musical guests perform two songs. Will the two-piece do a live version of 'Brokenhearted'? We'll just have to wait and see.
Check out Karmin's new single below and let us know what you think of it in the comments.
