Lexie & Christopher are a dance duo who reached the semi-finals of Britain's Got Talent in Series 12. They had been performing with each other for 2 years due to their audition, and before their audition Alesha asked Christopher whether Lexie was the boss, to which he replied 'well, she thinks she is'. They were both aged ten at the time of their audition.
In their audition, the pair performed to 'Dear Future Husband' by Meghan Trainor - 'because he's my future husband', Lexie explained. Christopher however did not appear to agree with this statement. In their audition the duo began by walking towards each other from differing sides of the stage, the pair then danced alongside one another in unison. Christopher then began to spin Lexie around, before the duo then concluded their performance with Lexie falling backwards and being caught by Christopher. After their audition, Alesha described the pair as 'like little butterflies', with Simon adding 'we’re going to remember your personalities as well'.
They began their Semi-Final performance with what seemed to be a ball, with Christopher dancing with a woman, before Lexie then walked upon the stage. The pair then danced in unison alongside one another to 'Bad Romance' by Lady Gaga, nearby a large silver archway, and with red spots of lighting making up the background. Lexie then stopped dancing with Christopher as the music then changed to 'Shut Up and Dance', by Walk The Moon, before the duo then went on to perform alongside one another once again. Their performance concluded with the pair walking behind one another, before they held hands following confetti falling down upon the stage. Amanda commented that Lexie had actually 'let [him] lead for once', with David joking that the pairs relationship actually reminded him of both '[him] and Simon'. They were eliminated by Public Vote at the end of the Semi-Final in seventh place.
