Robbie Williams, Mary J Blige, Shane Filan, Sinitta, Nicole Appleton (!) and, as previously announced, Olly Murs, will all be getting a free holiday to help some people judge some people on The X Factor.
Robbie will sit next to Sharon Osbourne in Hollywood, while Mary J Blige will help Nicole Scherzinger keep the sun off in Antigua.
Olly will be with Gary in New York and the holy trinity of Filan, Appleton and Sinitta will sit around Louis while he looks mildly perturbed in St Tropez.
There are some pictures of them all at work here.
You'll be able to see how it all goes this weekend. Expect a fair bit of crying.
