Chef and the owner of the best restaurant in UK, The Fat Duck, Heston Blumenthal has split with wife of 20 years, Zanna and is currently dating Suzanne Pirret.

Heston, 45, called his wife 'the reason for my success,' the Dailymail revealed.

Suzanne Pirret is an actress turned American cookery book writer.

Heston and his wife worked together to get their Fat Duck a reputation of the world's best restaurant, voted by Restaurant magazine in 2005.

The Fat Duck is a three-Michelin starred restaurant in Bray, Berkshire.

But the couple, who have three teenage children, admitted on Friday that the stress of work and turning the Blumenthal name into a multi-million-pound empire had taken its toll on their marriage, said the report.

Suzanne Pirret, also 45, was billed as a 'goddess' by critics after her book The Pleasure Is All Mine: Selfish Food for Modern Life was published and did really well.

Heston's spokeswoman confirmed that their marriage is over.

'Over the course of their marriage, they have built an extremely successful business, but one which has unfortunately taken its toll on their relationship.They remain good friends and devoted parents of their three
children who are their main focus,' she said, according to the report.
