The glamour model, real name Katie Price, was fed up of repeatedly being voted to carry out Bushtucker Trials by the public, and had just been nominated to do her seventh challenge.
'Katie Price has left the jungle,' ITV confirmed on its website.
Jordan, 31, was on the show for less than a week.
She hoped the experience would help her reconnect with the public following her divorce from Peter Andre, 36.
The couple met on the programme in 2004.
