When I'm all grown up, ain't no baby no more I can do the things I couldn't do before No more pony tails, I'll wear my hair up high Because I'm 17, & that's the reason why Now I'm all grown up & I'll go where I wanna go See who I wanna see, stay out late I'm all grown up & I'll do what I wanna do Be what I wanna be, gee I can hardly wait Well I'm goin' on dates every Saturday night & if he wants a kiss, I might say "All right" I gotta have me fun & I'll be ready to go I'm gonna go downtown, I'm gonna fill the floor Now I'm all grown up & I'll go where I wanna go See who I wanna see, stay out late I'm all grown up & I'll do what I wanna do Be what I wanna be, gee I can hardly wait Gee, I can hardly wait
