On her “Dignity” tour’s Mexico stop, former teen queen Hilary Duff was accused of lip-synching, reminiscent of the plot in her former film, The Lizzie McGuire Movie, where her greasy Italian love interest was indeed doing the dirty deed.

Miss Duff vehemently denied the allegations, blaming faulty Mexican equipment. Her people stand behind the star, insisting that she always performs live in her concerts.
