Mel lives in Los Angeles with her husband Stephen Belafonte and three children, but they are all upping sticks and heading to London as the ITV1 competition steps up a gear.
This weekend, Mel was seen on The X Factor selecting her final three boys alongside Spice Girl pal Emma Bunton at Judges' Houses in Mexico.
In the end, she has decided to take Andrea Faustini, Jake Quickenden and Paul Akister through to the lives.
Up until now the show has been pre-recorded, so Mel has been in Los Angeles with her family - but all that is about to change!
Yesterday, Mel posted a picture of herself, Stephen and daughters Phoenix, Angel and Madison as they made the most of the LA weather before heading to the UK.
You'd best pack some jumpers and a brolly, guys!
Commenting on her Instagram snap, she said: "Last afternoon of LA sun with my beautiful family, quick now let's get packing for London, whoop whoop here we come!!! #familytime."
Catch the first live episode of The X Factor this Saturday on ITV1!
