Set to embark on their headline 'Rock Out with Your Socks Out' world tour in May 2015, 5 Seconds of Summer perform their track 'Good Girls' live at Derp Con. The song is taken from their self-titled number one debut album.
The season 7 premiere guests featured some cast members we haven't seen much of for a while.
This year's Rotterdam event was definitely one to remember.
New album 'Flower Boy' comes later this summer.
