The big question - what are the Judges wearing tonight?
It's the question everyone wants to know the answer to - no not that one - what will the Judges be wearing tonight?
Take a look at the fab four's snappy dressing during the semi-finals and see if you can see any clues.
Speaking to The Mirror, Alesha said: "For the 2013 final I wore a dress that disguised my bump.
"This year I can wear what I want and I’m pleased with my look. Choosing an outfit for the Final is a lot of fun for myself and Amanda."
Make sure you're watching the Final tonight, 7pm, ITV, to find out the answer to this and that other little question.
