X Factor star Mary Byrne looks completely unrecognisable 12 years after starring on the hit ITV show.
Mary, who was dubbed “Tesco Mary” by adoring fans due to her former role as a supermarket checkout worker, has re-vamped her look after losing six stone.
Mary, now 63, wowed Simon Cowell, Louis Walsh, Cheryl and stand-in judge Katy Perry with her rendition of ‘I Who Have Nothing’ by Tom Jones when she auditioned for the show back in 2010.
Mary made it to The X Factor’s semi-final – which also starred One Direction and eventual winner, Matt Cardle.
She was known for her brunette locks – which she often styled into a high ponytail.
