Lady Gaga and Christina Aguilera are powerhouse superstars with loads of confidence. Given their impressive vocal ranges and ability to push the limits, we aren't surprised that they released singles that sound very similar. The overt tone of Gaga's R. Kelly collaboration, 'Do What U Want' reminds us a lot of Christina's 'Your Body.' Which "body" song do you like best?

Lady Gaga radiates confidence, and that was never more clear than in 'Do What U Want.' Mother Monster declares that her voice, mind and heart belongs to her alone -- but the right guy can have his way with her. R's smooth crooning is the perfect complement to Gaga's Christina-esque vocals, making this an instant dance hit.

Christina Aguilera's 'Your Body' is not so much about letting a man have his way with her as it is asserting her dominance over him. "I don't need to know where you've been, all I need to know is 'You in?" Xtina belts provocatively. Like Gaga's track, this one is all about following carnal desires.
