Happy Birthday to Calum Hood!

Happy Birthday to Calum Hood! The 5 Seconds of Summer bassist turned 19 years old today and celebrated at a bash with friends.

Calum has had an insane past year with his 5SOS bandmates. The group kicked off their headlining tours in Europe, North America and Australia. They also opened for One Direction on 1D’s Where We Are tour.

5 Seconds of Summer also released their debut album which hit #1 on the Billboard charts and released a follow-up live album this past December. The band will head out on another headlining tour this summer, as well.

We can’t wait to see what Calum and co. accomplish in this next year and we hope he has an amazingly fun birthday!
