Poor little Hilary. It's one thing to have everyone assume you don't write your own songs/sing your own tracks/are a natural blonde, but it's mega embarrassing to be totally caught out whilst performing. Yep, our favourite Duffer was a victim of the lip synching curse, where due to an 'electrical fault' the music cuts out and Hilary is left looking rather sheepish. Oh well, it keeps us entertained.
