The group took fans by surprise by performing several songs in the country's native language of Spanish, Variety Latino reported.

Two of the songs that the group performed were originally recorded in 1995. "Nunca Te Haré Llorar" and "Donde Quieras Yo Iré" are the Spanish versions of hits "I'll Never Break Your Heart" and "Anywhere For You."

Several fans shared clips of members Nick Carter, A.J. McClean, Brian Littrell, Kevin Richardson and Howie Dorough performing the songs on their social media accounts, particularly on Instagram.
