Who's better at singing Beyonce,Cristina Aguilera, or Demi Lovato?
None of them (just my opinion so don't get all pissed at me). The Beatles are better.
This question does not make sense.The fact that Beyoncé, Cristina Aguilera, and Demi Lovato are in the same sentence with a question that implies any of them are any good at singing at all is illogical.
Anyone but demi

i like em all but id have to say demis the best
