Tulisa Contostavlos's girl band topped our exclusive poll for the second consecutive week and the third time overall with their Justin Bieber/The Supremes mash-up and cover of Christina Aguilera's 'Beautiful', which impressed 35.5% of you.
The group moved several of the judging panel to tears with the latter performance, which they described as "everything that Little Mix is about".
Amelia Lily finished second with 25.7% of the vote, followed by Gary Barlow's final act Marcus Collins, who collected a healthy 18.4%.
Meanwhile, Digital Spy readers predicted that Kelly Rowland would see her acts Misha B and Janet Devlin finish in the bottom two tonight.
Misha received 15.5% of reader votes, while Devlin finished dead last with 5% after forgetting the words to her rendition of Hanson's 'MMMBop'.
