She won't get off the phone

She won't leave me alone

When I'm talking to that guy

She can be a real nightmare

Gets me to do her hair

And says it never turns out right

But when I put on a face

She can tell

Cause she knows me so well

Closer than my closest friend

Someone who will be there til the end

My sister, sister

Deeper than the deepest sea

No-one loves you like your family

My sister, sister

She reads my diary

She borrows clothes from me

And I never get them back again

And she

And she locks the bathroom door

Says "Five minutes more"

And an hour later I'm still not in

And sometimes we fight

Every family does (oh yeah)

But that can't change our love

Closer than my closest friend

Someone who will be there til the end (oh, yeah)

My sister (my) sister (my sister)

Deeper than the deepest sea (oh, deeper)

No-one loves you like your family (ooh)

My (my) sister (sister) sister

To celebrate the good times

To help me through the hard times

To bring me down to earth

Remind me what's important

And who comes first

And who comes first

Gotta tell you who I'm talking bout

My sister, sister (oh, yeah)

And who comes first

Ain't no doubt about it

Who I'm talking bout

My sister, sister

She watches out for me

I know she'll always be by my side

By my side (by my side) by my side

Closer than my closest friend (oh, yeah)

Someone who will be there (ooh) til the end

(I know you're gonna be there)

My sister, sister (I know it)

Deeper than the deepest sea (so much deeper)

No-one loves you like your family (my perfect family)

My sister, sister (my sister)

Closer than my closest friend (oh, closer)

Someone who will be there til the end (oh)

My sister (my) sister (my sister)

Deeper than (my…) the deepest sea

No-one loves you like your family

My sister, sister
