An amazing Australian band that plays pop-rock music. The full name of the band is 5 seconds of Summer but they are known as 5sos. It consists of Calum Thomas Hood, Luke Robert Hemmings, Michael Gordon Clifford, and Ashton Fletcher Irwin. This band is NOT A BOYBAND (if you think they are search up the definition of a boyband.) All four of the boys in the band are cute, adorable, and nice. They love their fans to death, and they never let the fame change them. They've been nice lads since the beginning and they still are. They're one of the most loved and popular bands ever!!!
Hey, have you heart of 5sos?

Yeah, aren't they the ones who sang the song She Looks So Perfect (slsp)?
