The McFly star beat his close friend Mark Wright to the title of King Of The Jungle.
The finalists came into a tight embrace as the result was announced, after which Poynter took his seat on the throne and was handed his crown by I'm a Celebrity...Get Me Out of Here Now! hosts Joe Swash and Laura Whitmore.
Speaking to Ant & Dec after his win, Poynter said: "I'm lost for words. It's been the best couple of weeks of my life, I wish everyone in the world could experience that."
Poynter was reunited with his McFly bandmate Tom Fletcher while posing for photographers in the I'm a Celebrity studio.
Fatima Whitbread and Antony Cotton finished third and fourth respectively in yesterday's episode.
Poynter is the eighth male winner since I'm a Celebrity began in 2002. He inherits his crown from last year's Queen Of The Jungle Stacey Solomon.
Poynter also received 59.1% of the vote to win I'm a Celebrity in Digital Spy's exclusive poll.
