Robbie Williams has joined Sharon Osbourne at The X Factor judges' houses.
The former Take That star was with Sharon at her home in LA this week to select the finalists in her category, and not for the first time.
Robbie previously appeared alongside Sharon during her previous stint as a judge back in 2013.
Robbie is the final guest judge to be revealed for this year's series.
Spice Girl Mel B will be joining Simon Cowell at his judges' houses later this month, replacing Cheryl who was previously linked to the role.
"Simon is hungrier than ever to win and wants Mel’s caustic and honest advice to spice up the ITV series," a source told The Sun newspaper this week..
They added to the tabloid: “She knows exactly what it takes to cut it in the business too. Simon is confident he’s got the winning formula.”
Earlier this month, Nicole Scherzinger was in the South of France with music and producer DJ Calvin Harris as she selected her finalists for the live shows.
And back in August, Alesha Dixon joined Louis Walsh in Ibiza. Alesha said: "Louis is crazy, we had such a laugh, I tried to advise him but I take no responsibility for the choices he made!"
The X Factor judges' houses will air later this year on ITV in October time.
Before that we've got the last of the auditions this weekend before boot camp begins with a bumper long episode on Sunday evening.
Those that survive this week will go on to the six chair challenge to compete for a place in judges' houses.
And don't forget all new Xtra Factor LIVE which airs straight after on ITV2, hosted by Rylan Clark-Neal and Matt Edmondson.
