TV chef Heston announced that he had left his wife of 20 years, Zanna, on 15 August, with a spokesman saying:

"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."

Heston, 45, does seem to have moved on quickly from Zanna though, as he is already dating US cookery book writer, Suzanne Pirret.
