Heston Blumenthal is reported to have split from partner and mum to his youngest child, Stephanie Gouveia.
The TV chef, who is a father of four, welcomed the child in 2018, shortly before the exchanged vows. Heston also shares three children with his ex-wife Zanna; Zack, 25, Jessie, 22, and Joy, 20.
Reports suggest the chef, 56, and French estate agent, 35, decided to call time on their relationship "some time ago". It remains to be seen whether the pair will need to go through divorce procedures, with conflicting reports as to whether their 2018 ceremony was actually an official marriage.
While a spokesperson for the star revealed they'd wed in 2018, a pal close to Stephanie claims that's not technically the case.
At the time, a spokesperson for the Michelin-starred chef said: "Heston and Stephanie are delighted to announce they've got married.
"They were spending some quality time together and decided to seize the moment."
The ceremony is said to have taken place while they holidayed in the Maldives, with the couple saying "I Do" in a beach-front reading.
However, a source told the Daily Mail : "Despite all the reports at the time, they were never married."
And a spokesperson for Stephanie told the same publication: "Marriage should be recognised by legal authorities. This wasn't. What happened does not constitute a marriage in a legally binding sense."
The Mirror has contact Heston's representatives for comment.
Last month, the chef outraged Christmas shoppers as he tried to sell mince pies with a bizarre twist. Known for his weird and whacky twists on classic foods, some fans thought his latest creation took his ideas a step too far.
Heston paired with Waitrose yet again for the festive period and released a range of foods and snacks. However, his take on the traditional mince pie divided shoppers.
The chef, who owns The Fat Duck in Berkshire, created a festive mince pie with a bizarre twist as it was made of a three-cheese pastry and filled with pear and fig mincemeat.
Reviewers of the items, which were available for £3.50 for a pack of six, complained about mixing sweet and savoury. One user on Twitter complained: "Definitely not on my repeat buy list. If it doesn't look like a mince pie it won't taste like one."
