Daniel Baldwin is jetting to the jungles of Costa Rica to replace newlyweds Heidi Montag and Spencer Pratt and join his brother Stephen as a castmember of reality TV show I'm A Celebrity... Get Me Out of Here!

Montag and Pratt walked off the survival show shortly after the first telecast aired in America on Monday night (01Jun09) - because they couldn't deal with the less-than-luxury conditions of jungle life and the stomach-turning challenges they were facing on the programme.

The couple appeared to be seriously turned off when teammate Patty Blagojevich and actor Lou Diamond Phillips were forced to eat tarantula on the show.

Network bosses at NBC aren't wasting any time in replacing the Pratts - they've drafted in Daniel Baldwin in to pair up with his younger sibling, according to reports on DailyFill.com.

And sources claim TV executives are lining up a second secret replacement.

This won't be Daniel Baldwin's first experience of reality TV - he was a part of U.S. show Celebrity Rehab with Dr. Drew last year (08).
