Selena is said to play
background vocals
[she said in a popstar interview that she and demi sanged a duet for the movie Princess Protection Program and demi wrote this song for the movie and for her BFF..so

I really don't know if its
true, but the song is
about her

Listen carefully to hear her

She was given the world
There's so much that she couldn't see
And she needed someone
to show her who she could be

And she tried to survive
Wearing her heart on her sleeve
But I needed her to believe

You have your dreams I have mine
You had your tears I was fine
Showed me what I couldn't find
When two different worlds collide
La dee da dee da!

And she was giving it all
watching from far away
She was given a role
Never knew just when to play
And she tried to survive
Living her life on her own
Always afraid of the thrown
But you've given me strength to find home


You have your dreams I have mine
You had your tears I was fine
Showed me what I couldn't find
When two different worlds collide

She was scared of rebirth
Left in the dark, falling apart
I can survive with you by my side
We'll be alright
I guess that's what happens when two worlds collide

You have your dreams I had mine
You had your tears I was fine
Showed me what I couldn't find
When two different worlds collide
La Dee Da Dee Da!

You had your tears I was fine
Showed me what I couldn't find
When two different worlds collide
When two different worlds collide (less info)
