Una Healy is among the contestants pitting their wits against Bear Grylls in the new competition Celebrity Bear Hunt on Netflix.
The eight-episode series premieres on Wednesday 5 February.
Teeing up what's ahead, Netflix said: "Holly Willoughby hosts this action-packed competition show that sees a group of unlikely celebrities dropped into the Central American jungle as prey for one of the world's most fearsome predators - Bear Grylls.
"Bear believes there's an action hero inside us all - even the celebs - but how strong is their will to survive?
"As Bear puts them through their paces, those who fail to impress will face the dreaded 'Bear Hunt' - a brutal game of cat and mouse where they'll be hunted down by Bear himself and, if captured, face elimination from the show."
Joining singer and presenter Healy in the series are model and TV host Leomie Anderson, singer Mel B, Strictly Come Dancing judge Shirley Ballas, Wimbledon winner Boris Becker, actor Kola Bokinni, and former rugby player Danny Cipriani.
Chef and rapper Zuhair Hassan (AKA Big Zuu), interior designer Laurence Llewelyn-Bowen, presenter Steph McGovern, model Lottie Moss, and actor Joe Thomas complete the line-up.
