Hilary Duff Denies Lip-Synching at a Concert in Mexico

Was singer/actress Hilary Duff really caught lip-synching at one of her concerts in Mexico over the weekend? Fans claim that at one point during the show, they were unable to hear Hilary's voice, even though she clearly appeared to be singing into her microphone.

Since critics shredded Ashlee Simpson for lip-synching on Saturday Night Live in 2004, Hilary's PR team knew they had to clear her name and do it quickly. "She was not lip-synching. It was faulty equipment. There was no sound coming out, but she was singing," her rep told People magazine.

Check out a brief clip from the concert and decide for yourself. Even in the parts where Hilary's voice is audible, I must admit that it sounds a lot like a digitally altered version.
