Mel B will find out if her sassy moves were enough to take the title on the results show tonight.

Following the surprise visit, Victoria - who is married to England soccer star David Beckham - said: "David and I are great friends with Tom and Katie. It was lovely of them to come down to rehearsals, a really nice surprise.
"Katie has told me before that she used to be a huge Spice Girls fan, so it was great for her to meet the other girls."
