Lyrics
The Chipettes:
Yeah, ooh, yeah, ooh
We got the power, yeah, we pack a punch
We up on top, and still heading up
We tough as nails, hold our heads up high
We never lose, 'cause we fight the fight
And wherever we go, we always have our girls
A sisterhood that reaches far and wide
And wherever we are, anywhere in the world
We're showing our pride
'Cause we are sisters
Yeah, we are sisters, woah-oh-oh
Yeah, we are sisters
Yeah, we are sisters, woah-oh-oh
Ooh, ooh, ooh, sisters, yeah
