As the Judges' Houses stage of the competition kicks off, Louis gathers his six groups on the beach where he reveals that Tulisa will be helping him to decide who his final three acts will be going through to the live shows.
And Tulisa's entrance is quite spectacular...
Showing off her curves in a white bikini, N-Dubz singer Tulisa - who left the show following the 2012 series - steps out of the sea and walks towards the groups.
With the use of slow motion, Tulisa seems to have left quite an impression on the groups (especially the boys!) as they dart towards her to give her hug, despite the fact that she's soaking wet!
In fact, X Factor's new boy band (name TBC), previously said of Tulisa's arrival: "We were all really pleased it was Tulisa and we definitely enjoyed her entrance out of the sea. It was like a rugby match when we all darted towards her!"
While the groups went to Bermuda, Simon Cowell invited the overs to his home in Los Angeles, Cheryl Fernandez-Versini took the girls to Nice, and Mel B took the boys to Mexico.
X Factor continues tonight at 9pm on ITV1.
