5 Seconds of Summer

What happens when 5 Seconds of Summer fans only have five seconds to meet the band? Well, they are learning just how short five seconds is thanks to Ellen DeGeneres.

The Australian boy band appeared on Thursday's episode of "Ellen," where the host gave a group of fans the chance to meet the group -- but only for five seconds. The host held a buzzer as the bandmates stood behind a partition. 

The group also performed their new single "Good Girls," giving the host a shout-out on stage by changing some lyrics to say "Ellen smells really nice!" The song is the fourth single off 5 Seconds of Summer's self-titled debut album, which recently surpassed a half-million in sales after dropping over the summer.
