LeAnn Rimes is denying anything was wrong with her when she performed on "X Factor" Wed. night, but if you watch this video, she sure seems to be way off, to say the least.

LeAnn comes out at the 1:22 mark. Look for her to burp or hiccup or something, shortly after she starts singing. Then, throughout her performance, you can barely understand her words, although at times, it seems like she's just skipping the words altogether, or something.

There's talk LeAnn was drunk during her performance, but she tweeted, quote, "In my 18 years of performing, I've never been anything but professional onstage."
