I have been waiting for this for years ever since Lady Gaga hit the scene, I have said how she sounds like Christina Aguilera in certain songs, and the two of them together....Padoww!

The rumor of a feud between the two powerhouse singers is just that, a rumor as Mama Monster made an appearance on The Voice and X-tina helped her out with her latest song "Do what you want" . Music to my ears, wow let's keep this going of more songs with the two of them together...Please :)
