But it was LeAnn who was so moved by the enthusiastic crowd's standing ovation that she wept openly onstage.
After the emotional performance, the potential reality star tweeted:
Wow, all I can say is wow!! London, I love you so much!!

Sound like the Brits love you guys, but probably not nearly as much as we love you.
We're so happy that you both come from the good ole' USA.
Congrats on the epic night!
Ch-ch-check out the electrifying performances…AFTER THE JUMP!!
