Jamie Lynn Spears broke down during the daunting trailer for Special Forces: World’s Toughest Test as the star is pushed to her limits.
The show, set to air on Fox in the US, will see a group of celebrities undergo challenges used to select Special Forces soldiers.
In a newly-released trailer for the programme, the 31-year-old singer and estranged sister of Britney Spears can be seen standing in a helicopter with her back to an open door.
A narrator ominously says: ‘If you should die, that is nature’s way of saying you failed,’ before the star leans back with her arms crossed and falls through the sky and into the sea.
