Jessica has three daughters from her relationship with Alistair
But Jessica has been left heartbroken after Alistair was found dead at home on Friday.
A representative for the star told The Sun Online: “Despite their break-up, Alistair was a really good father to their children.
“Jessica is politely asking for some privacy at this devastating time so that she can protect their three girls.”
A police statement read: “We were called shortly before 3am on August 11 following a report that a 35-year-old man had been taken to Royal Blackburn Hospital after he had been found at an address in Burnley.
“He was sadly pronounced deceased at hospital. His death is not being treated as suspicious and a file will be passed to the coroner.”
The former couple ran her first fashion business, Famous Frocks, before Jessica ended their relationship after Alistair was conviction of fraud.

He was found guilty of being part of an elaborate scam in 2013 and admitted money laundering before a judge at Preston Crown Court for which he received a 15 month jail sentence.
Since then, Jessica has gone on to set up another fashion business, ProdigalFox, with her sister Emma Deeks.
