Earlier during the AMAs, 5SOS showed off their punk rock energy with a cover of "What I Like About You" and it was honestly one of our fave performances of the night.
The guys totally old-school rocked the stage and looked like they were having the best time ever!
Watch the 5SOS guys accept their New Artist award, of course thanking the fans for the huge win. Totally adorable.
