Princesses Beatrice and Eugenie are wanted for the new series of Bear Gyrlls' Mission Survive.
ITV confirmed last week that a new series of the celebrity survival show was underway, with Bear saying: "I'm so proud of Mission Survive and all it stands for: endeavour, comradeship and overcoming fears.
"For me it is about understanding that sometimes we have to go through genuine adversity to come out the other side better, stronger and more empowered. It is such a privilege to get to do it once more with our BGV, Electus, betty team and here begins the journey to find the next ultimate survivor!"
According to The Sun on Sunday newspaper, show bosses are after royalty next year and hope that this year's finalist Mike Tindall can help.
Mike, husband of Princess Anne’s daughter Zara, made it to the last stages of the competition earlier this month but it was model Vogue Williams who Bear crowned his ultimate survivor.
However they hope he can help persuade his wife's cousins Beatrice and Eugenie to take part in the series.
A source said this weekend: “The team are keen to get another member of the royal family on board. Beatrice and Eugenie were suggested after Mike mentioned them. He’s obviously told the girls how much he enjoyed the experience.”
Filmed in Costa Rica, Bear's Mission Survive tests celebrities at every turn on the fundamental principles of survival: shelter, water, fire and food.
Challenges included abseiling down ferocious waterfalls, crossing perilous rapids, trudging through swamps and negotiating razor-sharp vines - not to mention contending with snakes, eating rats and scorpions... and drinking urine.
