Without a doubt, Pretty Little Liars‘ most infamous creeper, A, is the eyes and ears of Rosewood! But did you know that the sassy texter is also a pop culture maven at heart?

And today (September 20, 2012) ‘A’ is all over Britney Spears‘ shocking live performance on X Factor. The pop sensation is renowned for lip synching during live performances. (Words and dance moves don’t seem to mix well on stage.) So when she decided to go on camera and belt out a song au natural without the aid of synthesizers and background signers, we were all ears as was the Rosewood creepster. Turn on the volume, pretties, as Brit Brit croons a little ditty in honor of judge L.A. Reid’s birthday:

Dear Brit Brit, I see your lips moving but there’s no sound coming out of it. Oh wait — that’s because I turned off the volume. Now STFU and let the  man enjoy his cake.

Hmm. Britney didn’t sound bad at all and looked positively lovely with the candlelight gleaming in her blonde locks. Then again, this is A we’re talking about….total biotch.

Now it’s YOUR turn! What was your reaction to hearing Britney sing live on X Factor? Post your feedback in the comments!
