Xtina's Bobblehead I still believe is about gaga. But with some lyrics that suggests it's really her

[Spicechinodiva]

One of the best reasons to get a dekuxe is this gem right here..

 

Bobblehead. This immediately had references that I thought was about lady gaga..

Talking about with her clothes on she looks hot. But get her nude. You need the lights off cos her body is a nightmare on elm street. Got all the boys scared.

 

Mocks the whole paris Hilton dumb blonde trend. (I don't get it, like what, like really really).

 

So it could be about several people in the industry 

 

Then she exits the tracks with slamming people who play dumb to get the man and stay on top (another thing Paris actually admitted she did in the past and actually regretted it)

"I never play dumb to get what I want, and I'm always the one who comes out on top"

 

So I believe Bobblehead is referencing 

 

Lady Gaga , Jessica Simpson and Paris Hilton.
