Earlier this week the guys were basically mobbed by the fans when they arrived at the airport in Mexico City.
Not only were there tons of fans there waiting for them but extra security and police were rushed in too! The band even had to be escorted by police to their SOLD OUT show!
Watch footage of the whole thing above and click here to see a pic of their arrival at the airport.
