The integrated sponsorship was held by Iceland for nine years. The show returns for its 15th series later this year.
Gary Knight, the commercial content director at ITV, said: "This partnership opportunity delivers some of the highest audiences, as well as outstanding value across multiple platforms."
Last year, I’m A Celebrity… averaged 10.3 million viewers. The 2013 series was the most popular to date, attracting an average audience of 11.1 million.
Nick Canning, the joint managing director at Iceland, said: "The partnership has delivered fantastic results but the time is right for the Iceland brand to begin a new and very exciting chapter."
