The 31-year-old model will get 100,000 pounds per episode, along with a bonus 200,000 pounds "golden handcuffs" deal to keep her at ITV2, reports dailystar.co.uk.
Jordan's ex-husband Peter Andre has also inked a 105,000 pounds per episode deal for his new series, "Peter Andre-The Next Chapter", which starts in May on ITV2.
But sources says they were more worried about losing "What Katie Did Next" than 37-year-old Pete's show as she has got more "pulling power".
Her new series, which is already on air, covers her time in the celeb jungle, her split and reunion with Alex Reid, 34, and Christmas without Andre.
Cameras also followed the couple as they got hitched in Las Vegas just days after Alex won "Celebrity Big Brother" in January.
"Love her or hate her, Jordan is a huge hit for ITV2. Her series pulls in over 1.5 million people an episode, which is a massive audience," said a source from the channel.
