We definitely need to take up drumming if we can get biceps like these!
5 Seconds Of Summer drummer Ashton Irwin held his own gun show at the Vevo Certified Live concert in Santa Monica Monday.
Okay alright, his bandmates Luke Hemmings, Callum Hood and Michael Clifford were looking good, too!

The 5SOS guys played their latest single She's Kinda Hot for the first time live in Los Angeles, and finished the concert with their famous cover of What I Like About You.
What we like about Ashton is his amazing arms!
