Thanks to Adam Lambert performance on American Idol motown week..
I finally knows the title.. I've been looking for this song for weeks...

since I can't embed the youtube video, see the video here.

People say I'm the life of the party
Because I tell a joke or two
Although I might be laughing loud and hearty
Deep inside I'm blue

So take a good look at my face
You'll see my smile looks out of place
If you look closer, it's easy to trace
The tracks of my tears..

I need you, need you

Since you left me if you see me with another girl
Seeming like I'm having fun
Although she may be cute
She's just a substitute
Because you're the permanent one..

So take a good look at my face
You'll see my smile looks out of place
If you look closer, it's easy to trace
The tracks of my tears..

I need you, need you

Outside I'm masquerading
Inside my hope is fading
Just a clown oh yeah
Since you put me down
My smile is my make up
I wear since my break up with you..

So take a good look at my face
You'll see my smile looks out of place
If you look closer, it's easy to trace
The tracks of my tears

p.s.: Adam Lambert's performance on this song was so COOL!!! since he's not one of my favorite on this AI season8.
