The girls of Fifth Harmony recently stopped by Billboard to perform two songs off their upcoming debut album, including their hit single 'Bo$$' and a new song titled 'We Know.'

The former 'X Factor' contestants sat on bar stools and performed a stripped down version of their new hit single before introducing 'We Know' for the first time. 'Bo$$' sold 75,000 copies during its first week and debuted at No. 43 on the Billboard Hot 100.

In preparation for their new album, which does not have a title or release date yet, the girls traveled the United States in May and June as part of their Fifth Time's a Charm Tour. They will be hitting the road again this summer to join Austin Mahone on his tour as well.
