X Factor 2012: Tulisa travels to judges' houses in disguise!

Tulisa (The X Factor 2012)

X Factor judge Tulisa was reportedly smuggled into St Lucia for judges' houses in disguise this week.

The N-Dubz star was flying out to the Caribbean to film the next stage of the show, but had to share a flight with the acts in her category.

Keen not to spoil the contestant's surprise of finding out who their mentor was, producers disguised Tulisa in a flat cap, hoodie and shades, The Sun reports.

And the bizarre look worked, with the acts said to be unaware that Tulisa was on the same flight as them.

A source told the newspaper: “A vital part of the show is when the group find out who their mentor is and it has to be in a suitably glamorous location – not at Gatwick Airport!

“It was a logistical nightmare smuggling Tulisa on and off the plane and sneaking her past the contestants and into the resort.

“She loved the challenge, though, and had a right giggle getting dressed up.”

Tulisa will begin filming her judges' houses section later this week.
