Please help me to find this song:

This is a part of the song :

That's not big and I'm fabulous... Me and my girls we do it like this... bbw's do it like me... fabulous and thick F.A.T... fabulous and I'm big... yeah we do it like this... When I hit the scene everybody gasp's... In tight jeans I'm thick and I'm fabulous...

Not so easy I'm afraid.
