COULD one of the biggest stars on I'm A Celebrity … Get Me Out Of Here! be about to walk out of the jungle camp?

The tough living conditions, loneliness and terrifying wildlife in the jungle camp are all becoming too much for actress Maureen McCormick.

Cracks began to appear not long after The Brady Bunch star, famous for playing Marcia, was thrust into the thick South African bush with nine other personalities at the weekend.

And now betting agencies are tipping the 58-year-old will be the first to quit the Network Ten reality show.

On last night's episode, a stir-crazy McCormick sought the comfort of fellow campers Joel Creasey and Laura Dundovic, climbing into bed with the pair for a cuddle and a chat as dawn broke.

"Maureen is honestly one of the most bonkers people I've ever met," Creasey declared.

Her early morning attempt at bonding with the close-knit Australian bunch came after McCormick became lost in the middle of the night while trying to find the toilet.

"My mind isn't working properly," she said.

While the nine other stars clearly feel for McCormick, her qualms about the experience seem to be starting to grate.

There hasn't been one part of jungle life that the American actress has warmed to. If the going gets too tough, McCormick can always shout "I'm a celebrity — get me out of here!" and escape back to her normally comfortable life.

Elsewhere, the celebs continue to become acquainted with the daily challenges they must complete, with stand-up comic Creasey the first to be voted by viewers to get up close and personal with some critters in a Tucker Trial.

The 24-year-old funnyman was forced to put his hand inside five holes filled with an assortment of scorpions, snakes and tarantulas.

Despite declaring he hates wildlife, Creasey rose to the challenge and collected 10 stars, meaning 10 meals for his campmates.

TV personality Andrew Daddo also joined model and beauty pageant winner Dundovic in a Celebrity Chest task that involved sawing through a tree to retrieve a star.

Sunday's premiere of the big budget show saw Ten celebrate a strong ratings performance, with 1.19 million viewers tuning in. It also trended globally on Twitter.

I'm A Celebrity … Get Me Out Of Here! airs on Monday to Thursday at 7.30pm and Sunday at 6.30pm on Network Ten.
