"Twins" lyrics

I will have your back if you always have my back
You're my twin, la-la-la, you are my twin
I will love you back 'cause I have to have your back
We're connected at the hip, you're my twin, ha-ha-ha

You're the only friend that I let under my skin
Like we're living in the same skeleton
Sometimes I wanna cut you but I know I'll always love you
You're my twin, la-la-la, you are my twin
