The former X Factor judge has been spotted filming in Southampton (the one in Bermuda!) where Louis Walsh is currently hosting the Judges Houses stage of the competition.
Clad in a white bikini, the star showed off her trim physique on the beach as she was surrounded by crew members.
The singer was tipped to return to the show following her acquittal on charges of supplying drugs, and is aiding her former colleague as he picks which of the Groups category to take through to the live shows.
Louis will no doubt find Tulisa's input useful, as she remains the only judge in the show's history to win with a group after she secured victory with Little Mix in the first of her two years on the show.
Louis is the first of this year's judges to select his acts for the final.
Cheryl is expected to be joined by either Sia or Will.i.am in the South of France, while Mel B is set to head off to Mexico.
Simon Cowell meanwhile will be joined by Paula Abdul... and Sinitta in Las Vegas.
The X Factor will start on telly next weekend, Saturday August 30, at 8PM on ITV.
