The former X Factor judge is seen joining Louis Walsh in the Caribbean in a rather over the top entrance via the sea.
"When Tulisa came out of the water, we were all focused very hard… on her personality," Concept joked.
Of her return, Tulisa tells the groups: “It's so great to be back. I've heard some amazing things about you all, and remember, I'm the only judge to ever win with a Group.”
While Louis Walsh is in Bermuda with Tulisa and the Groups, Mel B and the Boys are in Mexico, Simon Cowell invites the Over 25s category to his home in Los Angeles and the Girls will sing for Cheryl Fernandez-Versini in Nice.
The final 24 acts will be whittled down to 12 as each judge picks their live show finalists.
As ever, X Factor host Dermot O’Leary will be on hand to congratulate the lucky three, and console those that fall at the final hurdle.
The X Factor airs tonight at 9PM on ITV and continues Saturday and Sunday evening at 8PM.
