The Pierces - Secret

no that song more goes with PLL.

Lady GaGa - Beautiful Dirty Rich (always makes me think of GG)
and Ke$ha - Take it off (maybe) but it could be just because I saw an amazing video of GG with this song.)
Ohhh and The All American Rejects - Dirty Little Secret
I will probably think of more later but those are the 3 songs that pop immediately in my head when I think of GG.

Pretending - Glee Cast

It could be like the background of a sad Chuck and Blair scene or something, because they are not together and are pretending like they have moved on from one and another but really secretly want to be with each other! <33
