Laryngitis? Taylor Swift just shakes it off.

Talk about insanely impressive: The 'Blank Space' singer performed at two different Jingle Balls in two different countries in just two days -- with one seriously killer case of laryngitis.

T. Swift revealed her unfortunate diagnosis on Twitter just as she was about to take the stage in L.A. at KIIS FM's Jingle Ball, writing:

"If you are aware and conscious of the fact that I have laryngitis and am going to need your help singing," Taylor reportedly told the audience in a raspy voice. "But I wasn't going to miss this. This is the best time I've ever had while having laryngitis, I can tell you that." We have to say we totally agree -- just check out her performance of 'I Knew You Were Trouble' in the video above. We actually think that her hoarse voice offers a totally sultry and awesome quality to the performance.

And she did the whole thing all over again just several days later in London, once again giving fans a warning about her illness/"frog"-like throat:

And yet she still killed it once again, performing 'Shake It Off,' 'I Knew You Were Trouble,' 'We Are Never Ever Getting Back Together,' 'Love Story' and 'Blank Space,' the last of which you can watch in the video below.

Taylor Swift = constantly killin' it, laryngitis and all.
