Tulisa 'Hid From X Factor Hopefuls On Plane'
Judge had to go incognito so she didn't spoil mentor surprise...
The former N-Dubz star is claimed by The Sun to have worn a cap, hooded sweatshirt and sunglasses on the long haul flight to St Lucia - so as not to give the game away to the hopefuls that she would be mentoring on the show.
A source said: "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."
