The new series of SAS Australia officially started filming in the Blue Mountains, NSW, this week.
But it seems, two of the celebrities have already quit Channel Seven's military-style show.
On Wednesday, the recruits were pictured completing a gruelling water challenge, but Manu Feildel and Brynne Edelsten were nowhere to be seen.

It's believed the celebrity chef, 47, and socialite Brynne, 38, weren't participating in the challenge because they had quit the show earlier.
Meanwhile, the other contestants were pictured next to a huge Jeep.
The car was seen being airlifted into the water, before the celebrity gang were spotted swimming around in the lake after seemingly escaping from the vehicle.
Some of the recruits looked nervous as they lined up at the side of the lake, holding their hands in front as they waited for their name to be called.
The network released the full line-up for the military-style competition on Monday, and it features a mixture of famous and controversial participants.
The series will feature Olympic runner John Steffensen, volleyball champion Kerri Pottharst, Bra Boy Koby Abberton, tennis player Mark Philippoussis and singer Pete Murray.
