Former 'X Factor' contestant lauds 'genius idea' to get Sharon back

Amelia Lily thinks it's a "genius idea" to get Sharon Osbourne back on 'The X Factor'.
The 18-year-old singer - who finished third on the programme in 2011 - admits she would have loved to have had the 60-year-old star, who was judge from 2004 to 2007, as her mentor because she's a "hero" and knows the ins and outs of the show.
