Swift's rep, Tree Paine, tells PerezHilton.com:
Wow. Wow. Wow.
Kanye is straight-up INSANE!!!!!
And though not NEARLY as flashy as her Billboard Music Awards performance, we think she KILLED it!
Check out our gurl Beyoncé doing what she does best - breaking it effing DOWN - during her performance of Run The World (Girls), off of her her latest album, 4, last night on The X Factor France (above)!
Hot damn, is she taking Europe by storm, or what?
Now if only the actual album had this much energy!
