Tulisa 'Hid From X Factor Hopefuls On Plane'

The X Factor judge Tulisa Contostavlos reportedly had to wear a disguise to hide from contestants on the show as they shared a plane for the Judges' Houses section of the show.

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."
