Yes it is rather easy the first was when she was in the micky mouse club , the later when she started to sing - think of her first hit lyrics :

Oh baby baby, how was I supposed to know
that something wasn't right here
Oh baby baby, I shouldn't have let you go
and now you're out of sight, yeah
Show me how you want it to be
tell me baby cause I need to know now
oh because

CHORUS
My loneliness is killin' me (and I)
I must confess I still believe (still believe)
When I'm not with you I lose my mind
give me a sign,
hit me baby one more time

Oh baby, baby, the reason I breathe is you
Boy you've got me blinded
Oh pretty baby, there's nothin' that I wouldn't do
It's not the way I planned it
show me how you want it to be
tell me baby cause I need to know now
oh because

CHORUS

Oh baby baby, how was I supposed to know
Oh pretty baby, I shouldn't have let you go

I must confess that my loneliness
is killing me now
don't you know I still believe
that you will be here
and give me a sign
hit me baby one more time

CHORUS

I must confess (my loneliness)
that my loneliness (is killing me)
Is killing me now (I must confess)
Don't you know I still believe
that you will be here (im losin' my mind)
and give me a sign
hit me baby one more time
