Don't go around with a doubt in your mind
You know, baby, I'm not the cheatin' kind because

(You'd better believe it)
Whoa... oh... whoa... you'd better believe it, baby
(You'd better believe it)
Mmm

Somebody's been lyin'
Because I've been so true
Now stop your cryin'
And your sobbing too

You'll feel so much better when you do
You know, baby, there's no one else but you because

(You'd better believe it)
Whoa... oh... whoa... you'd better believe it, baby
(You'd better believe it)
Mmm

How could you let them get under your skin
The story you heard was just a big lie
I know within my heart I've committed no sin
So baby, there's no reason to cry, whoa... whoa... yeah, yeah, yeah, yeah

(You'd better believe it)
I know, I know, I know, baby, you'd better believe it, yeah, yeah
(You'd better believe it)
