Answer 1

The song in the trailer of "Uptown Girls" is called "Complicated" and is by April Lavigne.
It is on her album "Let Go"
It is such a great song.
Lyrics below:
Uh-huh,
Life's like this
Uh-huh, uh-huh
That's the way it is
'Cause life's like this
Uh-huh, uh-huh
That's the way it is

Chill out,
What you yellin' for?
Lay back, it's all been done before
And if you could only let it be
You will see

I like you the way you are
When we're, driving in my car
And you're talking to me
One on one
But you become

Somebody else
'Round everyone else
Watchin' your back
Like you can't relax
You're tryin' to be cool
You look like a fool
To me

Tell me
Why do you have to go and make things so complicated?
I see the way you're
Acting like you're somebody else gets me frustrated
Life's like this, you
And you fall and you crawl
And you break and you take
What you get and you turn it into
Honesty Promise me I'm never gonna find you fake it

No, no, no

You come over unannounced
Dressed up like you're something else
Where you are and
Where you sat, you see
You're making me
Laugh out
When you strike a pose
Take off all your preppy clothes
You know
You're not fooling anyone
When you become

Somebody else
'Round everyone else
Watchin' your back
Like you can't relax
Tryin' to be cool
You look like a fool
To me

Tell me
Why do you have to go and make things so complicated?
I see the way you're
Acting like you're somebody else gets me frustrated
Life's like this, you
And you fall and you crawl
And you break and you take
What you get and you turn it into
Honesty Promise me
I'm never gonna find you fake it

No, no, no...

Chill out,
What you yellin' for?
Lay back, it's all been done before
And if you could let it be
You will see

Somebody else
'Round everyone else
You're watchin' your back
Like you can't relax
You're tryin' to be cool
You look like a fool
To me, to me

Why do you have to go and make things so complicated?
I see the way you're
Acting like you're somebody else gets me frustrated
Life's like this, you
And you fall and you crawl
And you break and you take
What you get and you turn it into
Honesty Promise me I'm never gonna find you fake it

No, no

Why do you have to go and make things so complicated?
I see the way you're
Acting like you're somebody else gets me frustrated
Life's like this, you
And you fall and you crawl
And you break and you take
What you get and you turn it into
Honesty Promise me I'm never gonna find you fake it

This is the song performed live by April on Youtube.com (being a live performance, it's not all that great a clip):

Answer 2

"Why did you have to make this so complicated?" is that the line that I'm hearing? That was on the movie trailer. Sounds like some of it is in the TV trailer.

I've got the UPTOWN GIRLS soundtrack but don't see that song on there. I'll listen to it for you tonight and see if it's on the DVD. Maybe it's "Time" by Chantal Kreviazuk.
