Who can make you mad when you're having a blast   I can, I can   And who can pick you up when you feelin' like you suck   I can, I can      And who knows what you think without you saying anything   I do, I do   Who had you figured out and never had a doubt   I did, I did      Haven?t you heard, I'm Supergirl?   You don?t wanna mess with me   I got your back, I know your every move   And I got everything you'll ever need      I can make you hang on every single word   Like this, like this   It could be my vibe, maybe it's my mind   Could be my kiss, could be my kiss      But when I'm around you   There?s nothing I can't do, I'm at my best, I'm at my best   Well, maybe I'm so good 'cause your standing in the room   You wish, you wish      Haven?t you heard, I'm Supergirl?   You don't wanna mess with me   I got your back, I know your every move   And I got everything you'll ever need      I'll take your headache away   Give you one another day   I'll be the reason that you live   I'll show you what you've always missed      Haven?t you heard, I'm Supergirl?   You don't wanna mess with me   I got your back, I know your every move   And I got everything you'll ever need      I'm Supergirl   I got your back, I know your every move   And I got everything you'll ever need      I got everything
