Perhaps Jahmene's rendition of 'I Say a Little Prayer' did it for you? Maybe Rylan's Rihanna and J-Lo mash-up had you shaking your booty? Did Christopher's 'Waiting For a Star To Fall' have you rushing to the phone?
Or did James Arthur's version of 'Sexy and I Know It' get you hot under the collar? Maybe Lucy Spraggan impressed you with her version of 'Titanium'? District3 were begging for your votes with 'Beggin'/'Turn Up the Music', but have they won your vote tonight?
Or perhaps MK1, Kye Sones, Jade Ellis, Ella Henderson or Union J impressed you? Either way, have your say in our poll below, and elaborate on your choice in the comments section!
