Jodie, who is set to appear on the Channel 4 reality show this weekend, announced the split today. It is believed she and David have been separated since before Christmas.
The couple had been together for 10 months prior to their West Sussex wedding in August, however the spark has already fizzled out.
Confirming her split to The Sun, Jodie said: "It's with sadness that David and I have separated. My priority remains my son Indio."
This was Jodie's second marriage. In 2005, the motoring enthusiast tied the knot with entrepreneur Aidan Butler. The couple split 18 months later.
In September 2011, Jodie and her then-boyfriend, Argentinian polo player Andrea Vianini, welcomed their first child together, son Indio. Unfortunately, this romance did not last and Jodie and Andrea split in 2013.
This Sunday, Jodie will be starring alongside a host of famous faces in the new series of The Jump, which is filmed in Austria.
Although not in the initial lineup, Jodie was brought in to replace Sally Bercow after she broke two ribs during training.
