But according to Xtra Factor co-host Rylan Clark-Neal, that may not be their actual makeover...
It's tradition for the finalists to have a glossy makeover after Judges' Houses and just before making their live show debut, but Rylan has suggested the actual makeover has yet to happen.
Speaking on ITV's This Morning, Rylan said: "I've heard through the grapevine that this isn't the full makeover. I've heard this is just a little polish and in a couple of weeks you might see a bit of a transformation.
"You saw the VT [at the end of the last episode], a quick snipped of them. Normally that is the point where they all go, 'This is our new look!' They've done [those photos] for the profile VTs before they go on stage but, like I said, I heard through the grapevine...
"My styling team is the styling team working on the show and I said, 'They look great, amazing, but not as made over.' I heard in a couple of weeks they may be!"
