Running Wild with Bear Grylls - All Seasons

Courteney Cox, Julianne Hough, Vanessa Hudgens, Nick Jonas and Lindsey Vonn are set to take on the great outdoors on the upcoming season of NBC's adventure series "Running Wild with Bear Grylls."

Courteney Cox, who is set to travel to Ireland with Grylls, gained overnight fame as Monica Gellar on NBC's Emmy Award-winning comedy "Friends." For six seasons, Cox was seen in her Golden Globe-nominated role on "Cougar Town," which she also executive produced and directed. She has starred in the hit horror comedy franchise "Scream," as well as "Mother's Day," "Ace Ventura: Pet Detective," "Bedtime Stories," "3000 Miles to Graceland," "Mr. Destiny," "Cocoon: The Return," "The Longest Yard" and "Barnyard."

Julianne Hough, who will travel to Africa with Grylls, is an actress, dancer and lifestyle entrepreneur. She recently starred in the acclaimed "Grease: Live!" telecast and is a two-time professional champion and Emmy Award-winning choreographer for "Dancing With the Stars."

Vanessa Hudgens will venture to the Sierra Nevada Mountains. Most recently Hudgens received critical praise for her role as Rizzo in "Grease Live." Hudgens has also starred in several films, including "Spring Breakers" and "Sucker Punch." Hudgens will star this fall in the new NBC comedy "Powerless."

Also traveling with Grylls to Sierra Nevada is Nick Jonas, who currently stars on the critically-acclaimed DirectTV series "Kingdom" and will next be seen in the indie film "Goat" this fall. Jonas will release his upcoming album, "Last Year Was Complicated," as well as kick off his multi-city North American tour in June.

Alpine skier and Olympic gold medalist Lindsey Vonn will also go to Ireland. She has won four World Cup overall titles and won the downhill at the 2010 Olympics, the first time an American woman captured gold in this event. This year Vonn won her 20th World Cup title and crystal globe, setting an all-time record for men or women.

On Running Wild with Bear Grylls: The Challenge, Bear Grylls is taking it up a level by teaching his celebrity guests essential survival skills that they'll have to master and then prove they can use in a high-stress situation. With more daring, epic challenges that span from the snowy peaks of the Canadian Rockies to the deserts of the Great Basin to the volcanic rainforests of Costa Rica, are Natalie Portman, Ashton Kutcher, Florence Pugh, Simu Liu, Anthony Anderson, and Rob Riggle up for "The Challenge"?
