2D Game - GUIText doesn't shake with the camera

Hi first of all this is my first question here. Im from Argentina so sorry if i miss any word :).

I'm making a 2D plataformer game, every time my player shoots an spell and it hits an enemy the camera shakes a little. If the spell is bigger the amount is higher.

I'm building a prototype to get the basics to work. Now im setting the UI and i find this problem, when the camera shakes the GUIText doesn't follow. I want to know if there is any way to achive this by parenting the GUIText to the camera or other gameobject. I dont want to mimic the effect making 2 separate functions one for the camera shake and other for the GUI because i use randoms and acceleration and i dont think it can match the movement of both.

I have tried to set the GUIText as a child of different objects in the scene but it didn't work. I have also seen that i can use 3dText but is it correct to do so? and i have some problems with the 3dText rendering.

EDIT: The Blue bar on top is a sprite animated it works as an UI or GUITexture but it doesn't have the camera shake problem because it uses other kind of positioning.

Here is a screenshot:

You can see the GUIText on top of the 3dText
